Dhismaha Fan

Turbine kasta oo aad aragtay ayaa raacda manhajka la midka ah: rotor kaliya oo weyn sida suurtogalka ah, sida sare u sii. Waxay shaqeysaa si cajiib ah, waxayna u baahan tahay xamuul, dhul furan iyo sano oo oggolaansho ah. Su’aashayada waa mid ka soo horjeeda. Ma rotor yar oo badan, ku dhisan meelaha ay magaalooyinka hore u yihiin, samayn kartaa korontada qiimaha macno leh? Fikrada Fan Wall waxaa markii ugu horeysay la soo jeediyay Local Solar System Foundation 2020; boggani waa mid furan oo la cusbooneysiiyay.

Boggan waxaa loogu talagalay dadka maalgalin kara, dhiso ama tijaabiyo fikradda. Waa si gooni ah aan buug iibka. Waxaan ku socday tirada naqshadeyntayada koowaad, ka helay meesha ay fashilmaan, dib u qaabeeyey, oo ku socday tirada mar kale. Version gaaban: a wall of computer fans on a facade ma shaqeyn karo, taaj oo kale ee rotors ducted weyn on xagal dabaysha saqafka ah waxay sameyn kartaa korontada dhabta ah, iyo ma dhici doono panels qorraxda ku saabsan qiimaha haddii aan waxyaabo badan oo aan isku dayno si fiican u soo bixi. Fiiri kasta hoos ka yimaadaa noo furan qaabka (code, data).

Version 1, iyo sababta ay u shaqeyso

Fikradda koowaad waxay ahayd dhismaha facade, 40 m dheer iyo 15 darajooyin sare, ku jira oo ku saabsan 110,000 taageerayaasha 120 mm, mid kasta oo ka socda dib si ay mooto uu noqdaa generator. Waa sawir qurux badan. Waxay ku fashilantay saddex sababood, si waafaqsan muhiimadda.

**1. Hawada ma gudan karo a wall xiran. ** A turbine qaadaa tamarta ka hawada oo ku qulquli iyada. Fasad adag oo dabaysha ka tagto (injinyarada waxay ugu yeeraan joogsi) oo hoos u dhacaysa, hoos u dhacday iyo dhinacyada. Haddii qof kasta oo jecel uu lahaa 30 cm ka dibna, fur dhinaca iyo korka, sii socoshada soo saarta xad adag: dhammaan hawada galaya 1,800 m² ee jecel waa in ay ka baxaan iyada oo ku saabsan 39 m² ee u dhexeeya, sidaas darteed waxaa laga yaabaa in ay soo gudbaan jecel aan ka badan 2.2% ee dhaqdhaqaaqa dabaysha. Power la socdaa cube ee xawaaraha, sidaas darteed derbiga si fiican u hoos 0.01% ka mid ah waxa taageerayaasha isku midka ah samayn lahaa taagan xor ah. Miisaanka ka dambeeya dhab ah ee hawada lagu dhaqo waa isku mid: 0.2 ilaa 0.6 m / s oo ah qulqulka hawada ee dabaysha ilaa 5 m / s (Salonvaara et al., 2007). Switch the 3D model above to version 1 to see it: the wind streaks stop at the wall and slide away.

**2. Tiny Blades shaqeeyaan si xun. ** A 120 mm fan Blade waxaa jira xidid ah oo ku saabsan 2 cm. Hawada ku hareeraysan waxay u wareegtaa tirada Reynolds ee 10,000, nidaam halkaas oo galoofyada ay ka helaan inta badan heerka sare-u-qaadashada: airfoils siman ayaa hagaajiya “in ka badan amar weyn” korkiisa tirada Reynolds ee muhiimka ah ee ku saabsan 70,000 (Lissaman, 1983). Turbinada miisaanka sentimitir ee la tijaabiyay waxay gaadhi karaan awooda ku dhow 9% (Howey, Bansal iyo Holmes, 2011); a 10 cm kombiyuutarka-fan rotor loo isticmaalo sida turbine soo diray 28 mW at 5 m / s, ku saabsan 4% awoodda dabaysha oo dhan iyada oo xisaabtayada (Federspiel iyo Chen, 2003). Fannaaniinta kombiyuutarka ayaa loo qaabeeyey inay hawada ku dhaqdaan, oo aan lagu dhaqmin.

**3. Kun oo generators yar yar waxyaabo yar ay sameeyaan. ** A fan motor soo bandhigay qayb ka mid ah watt at volts qaar ka mid ah ayaa laga yaabaa in ay lumiyaan 10 ilaa 40% ee diode rectifier keliya. Qiimahayaga dhexe ee silsiladda oo dhan ka fanka in grid waa 54%.

Inkasta oo aan la tixgelin sababta koowaad oo dhan (a wall madax-bannaan ee taageerayaasha), version 1 ku kacaysaa in ka badan $4.20 per kWh on a windy coast and $18 magaalada, labaatan ilaa boqol jeer qiimaha rooftop qorraxda.

Fiisikada oo dhigaysa xaddidaadaha

Xoogga ay dabayshu ku qaadato meel A waa P = ½ ρ A v³, oo leh dhererka hawada ρ = 1.225 kg/m³. Cube waa wax kasta: at 6 m/s mitir laba jibbaaran qaadi kara 132 W, at 12 m/s 1,058 W. Sanad ka badan, daaqadda magaalada oo leh 4 m / s dabaysha dhexdhexaad ah waxay bixisaa ku saabsan 75 W per m²; xeebta la muujiyey ee 6.5 m / s ku saabsan 321 W per m².

Betz xaddidaadda. No rotor furan ka soo bixi kartaa in ka badan 16/27 ≈ 59.3% ee awooda ku qulqulaya qaybta, sababtoo ah hawadu waa in ay sii socdaan oo ka baxay jidka.

Waa maxay rotor labaad ku dari kartaa. Labada rotors in series (sida heerarka ee matoorka jet) waxay gaadhi karaan ugu badnaan 16/25 = 64% of awooda ka qaybgalka mid rotor ah, iyo aan xad lahayn oo badan oo kaliya 2/3 (Newman, 1986). A jet engine stackstages sababtoo ah waxay ku dhaqaajin hawada ka mid ah core xaddidan oo leh farqiga cadaadis weyn ka soo baxa dabka. Dabaysha bilaashka ah ma bixiso cadaadis noocaas ah: mar kasta oo dheeraad ah oo heerka hawada sii yareysa, iyo hawada hooseeya ayaa ku wareegsan qalabka. Miisaanka miisaanka ee rotorka dabaysha ee la isku rogay waxay u dhexeeyaan 0 ilaa 60%, laakiin tijaabooyinka ugu dambeeyay ee la xakameeyey ayaa ku kala duwan 2 ilaa 10% (Adema et al., 2026 dib u eegista).

Waa maxay vanes stator ku dari kartaa. A rotor ka tagaa hawada wareegaya, iyo wareegga waa tamarta la waayey. Markay tahay tirada hoose ee xawaaraha xawaaraha ah ee rotor yar, khasaaraha waa weyn yahay: rotorka Glauert ee wanaagsan wuxuu gaarayaa 0.42 marka la barbardhigo xawaaraha xawaaraha ah ee 1, 0.51 at 2 iyo 0.57 at 5. Vanes Fixed ka dambeeya rotor ka dibna qayb ka mid ah waxaa laga soo kabsan karaa. Cidna ma miisaamin tan turbiin hawada; on diyaaradaha propellers sida vanes siiyey 2 ilaa 5% (Li et al., 2017).

Waa maxay kanaalka ku dari kara. Kanaalka leh daboolka siman (waxaa loo yaqaan “lens of wind” ee Jaamacadda Kyushu) hoos u dhigi doona cadaadiska gadaal ka socda rotor-ka oo hawada ka soo qaadi doona. In tijaabooyinka tuulada-tiir ah diffuser compact brimmed kor u qaaday saamiga awoodda ka 0.37 ee rotor barafaysan in u dhexeeya 0.7 iyo 0.88, ku saabsan dhul ballaaran, laakiin kaliya 0.48 ilaa 0.54 ku saabsan brim oo dhan (Ohya iyo Karasudani, 2010). Taasi waa waxa la qabto: mitir laba jibbaaran oo ah * frontal *, dhuumaha ma aysan guuleysan xadka Betz, “waxqabadka awoodda kororka faahfaahinta kor ku xusan 3 weligood lama gaarin”, iyo ducted turbinadu waxay lahaayeen “50 sano ka badan. Tan iyo markii aan wax guul ganacsi ah” (van Bussel, 2007). Tijaabada ugu qaalisan ee la soo dhaafay, FloDesign / Ogin, waxay ka saartay turbinadeeda lix bilood gudahood waxaana la joojiyay 2017 (Gipe, 2017).

Miisaanka waa muhiim sababtoo ah tirada Reynolds. Waxaan xisaabnay rotor ugu fiican ee suurtogalka ah oo leh cabbir kasta oo leh qaab-momentum ah (Glauert’s optimum with wake rotation, tip iyo hub losses, iyo lift-to-drag ratio oo ku dhaca lambarka Reynolds, laga bilaabo airfoils hooseeya oo la miisaamiyay sida Selig’s SG6043):

Dhererka rotorka	Blades, tiir-xawaare ratio	Reynolds tirada (75% radius)	Naqshadeynta ugu fiican Cp
4 cm	8, 1.25	4,500	0.23
12 cm (kombiyuutarka fan)	8, 1.5	12,000	0.29
25 cm	8, 2.0	20,000	0.36
50 cm (module la hagaajiyey)	6 ilaa 7, 2.5	43,000	0.39 ilaa 0.40
1 m	6, 3.0	74,000	0.42
7 m (turbine yar)	8, 4.5	265,000	0.49

Kuwaas waa daaqadaha loogu talagalay sabab-dhismeed, ka hor khasaaraha dhabta ah ee adduunka. Sida baaritaanka, 39 cm turbiin la qaadi karo oo loogu talagalay ujeeddada ayaa lagu tijaabiyay 0.32, halkaasoo moodelkeena uu siinayo 0.39 oo ah cabbirkaas (Kishore, Coudron iyo Priya, 2013): sidaa darteed waxaan u maleyneynaa in qalabka ugu horreeya uu gaaro 65 ilaa 90% qiimaha naqshadeynta, iyo wax yar oo ka badan rotor-yada sentimitir, halkaas oo kala soocida laminar ay ka sarreyso.

Waddooyinka hawada. A module fixed kaliya u isticmaalaan qayb ka mid ah dabaysha ku soo duulay in ay. Xoogga wuxuu ku dhacaa si siman oo leh cube-ka geeska isbeddelka ee rotor-yada furan iyo si fiican u sii socda (Tamaro et al., 2024; Richmond-Navarro et al., 2022). Iyadoo dabaysha caadiga ah ee ka jirta, modul oo ku wajahan waxay haystaan ​​qiyaastii 47% ee tamarta rotor-ku dhejisan ayaa heli doonta. Version 1 la aaminsan yahay 100%.

Naqshadeynta la hagaajiyey: taaj oo ku yaal xagga dabaysha ee saqafka

Ka qaad wax kasta oo kor ku xusan iyo naqshadeynta in ka badan oo uu qoray: rotors weyn halkaas oo Reynolds tirada waa meeris, in dhuumaha ilaaliya oo ay u dhaqaajiyaan, taagan oo bilaash ah halka hawada ku gudbi karaan, la soo wajahan dabaysha ka jirta goobta dhisme halkaas oo qulqulka ugu xooggan. Meeshaas waa xagga saqafka. Hawada oo ku dhuftay facade sare u kacdo iyo wareegyada ka badan xadka; kor saqafka upwind xagga dambe ee dabaysha waa 1.06 ilaa 1.25 jeer ka dhaqso badan tahay xagga sare ee saqafka, laakiin kaliya 0.38 jeer marka ay xadka waa downwind (Mertens, 2006).

Module kasta waa 725 mm square: a 0.5 m toddoba-blade rotor in dabaysha-lens compact, shan vanes stator oo soo kabashada qaar ka mid ah wareegsan iyo qaadashada 50 ilaa 300 W jeneraator, a ilaaliyaha birta ah iyo mid ka mid ah guddiga awoodda la xidhiidha max power-point raacidda. Labada riix si ay u sameeyaan 1.45 m taaj dheer on tareenka birta ka sarreeya parapet. Mid qof ayaa ka qaadi kara module ah oo ka baxa iyo isku beddel.

Blades ma aha wax la saadaalinayo. Naqshadda waxay u naqshadeysaa tirada Reynolds ee ay dhab ahaan u arki doonaan, oo ku saabsan 45,000 at 6 m / s: xididka 62 mm oo ku dhow xididdada sicir-dhimista ilaa 36 mm xagga sare, ka soo noqnoqoshada 38 ° ilaa 10 °, isku dheelitirka qaabeynta xawaaraha 2.5. At 6 m / s rotor ku wareegaya in ka badan 700 rpm; timaha u dhaqdhaqaaqa in ka badan 30 m / s in 10 m / s dabaysha, ka yar badhka 79 m / s ee timaha weyn ee turbine.

Tirada run ah

Mitir laba jibbaaran oo ah dhul ballaaran ayaa ah habka ugu wanaagsan ee la barbardhigo: dhismo, daaqado iyo xadgudub wadada oo dhan waxay ku tartamayaan wax isku mid ah, oo ah duufaan. Qiimaha dhexe, oo leh heerka pessimistic-to-fiican oo buuxa ee data qaab. Tamarta waxaa ka mid ah jihada dabaysha, qalalaase (5 ilaa 15% khasaaraha) iyo helitaanka (92 ilaa 97%). Qiimaha tamarta: 20 sano oo ah 7% qiimaha dhimista dhabta ah, dayactirka 2 ilaa 5% ee maalgashiga sanad kasta.

Waxa miiska ku qoran:

• Waddooyinka waxay ku kasbadaan meel, kaliya. Per m² frontaal ah, modules ducted (B) ku dhuftay rotors isku mid ah ee furan (B0) by ku saabsan 10 ilaa 30%, inta badan sababtoo ah waxay u dulqaadan jihada dabaysha si ka fiican. Waxay sidoo kale bixiyaan ilaaliye, tilmaam xasillooni iyo meel loogu talagalay stator.
• Rotor labaad ma bixiso. Waxay ku dartaa 6% tamarta 16% oo dheeraad ah. A jet-engine-style multi-stage dabaysha module waa physics-ka fog, ma aha damac-ka fog.
• Uun waa modules windward bixisaa. A taaj oo dhan saqafka ku wareegsan kaliya ka helaan 55% per module marka la barbardhigo dhinaca windward keliya, sababtoo ah dhinacyada kale ayaa ka soo horjeeda dabaysha ka badan inta badan ee waqtiga. Ku saabsan dhismaha soo jeedinta (40 × 20 m, 45 m dheer) taajka caqliga leh waa dhinaca dabaysha oo kaliya: 60 m², ku saabsan $ 64,000, ku saabsan 9,500 kWh sanad kasta goobta dabaysha, 2,600 magaalada. Lacagta la mid ah ee dayuuradaha qorraxda ee daaqadda ayaa iibsadaa 155 m² panels kaas oo sameeya 35,000 kWh sanadkii.
• Magaalada ma awoodi karto inay la tartamto. Dhismaha-dhismaha dabaysha yaryar waxay leedahay diiwaan xun: 26 turbinada ee Warwick Wind Trials ayaa dhexdhexaad ah 0.85% faa’iidada awooda (Encraft, 2009), iyo saddexda turbinada ee London ee Strata Tower waxaa la xiray kadib markii qaylo iyo cabasho dhaqdhaqaaqa.

Si loo mideeyo, maraakiibta hawada yar ee Mareykanka waxay ku dhexmartay 14 ilaa 16% awooda iyo $6,680 to $9,630 oo ah kW kasta oo lagu rakibay 2024 iyo 2025 (Warbixinnada Hawada ee PNNL). Our taaj dhulka ku saabsan $ 6,300 per kW qiimeeyay, in ay isku mid ah, taas oo ah calaamad qiimaha la saadaalinayo ma aha fantasiya.

Waa maxay la xaqiijiyay, loo malaynayo iyo speculative

Proven (kitaab dugsi ama la tijaabiyay): awoodda dabaysha iyo xadka Betz; 16/25 silig laba rotor ah; in dhuumaha korontada ku kordhiyaan meel kasta oo rotor ah laakiin aan ka baxsan Betz ee goobta hore; in weelka yar ee Reynolds ay hoos yimaadaan tiro ku saabsan 70,000 ay waxtar u lumiyaan; in derbiga xiran uusan lahayn qulqulka; in darbiga cidhifka uu dhaqaajiyo qulqulka hawada; in dhismaha-mounted turbinada yaryar magaalooyinka ayaa si xun u shaqeeyaan.

Plausible (la taageeray, laakiin aan la miisaamin qaabkan): a 0.5 m rotor loogu talagalay Reynolds 45,000 gaadhay saamiga awoodda ku dhow 0.3 baraf iyo 0.55 ee gobolka rotor in biyo xireenka compact brimmed; 75% silsilad ka faa’iido rotor si grid la 50 ilaa 300 W generators iyo module-level MPPT; ku rakiban qiimaha u dhow $ 1,000 per m² u ah mashruuca koowaad.

Speculative (waxaa la ogaan doonaa): sida badan oo ducts isku dhafan dhinac ka dhinac u dhintaan midba midka kale (Waxaan aaminsanahay 10 ilaa 30%); xawaare-u-dhimista dhabta ah iyo qalalaase ku yaal taaj ku yaal dhisme la siiyay; nolol maalmeed ee kunka ah ee bearings in ka badan 20 sano oo dabaylo, baraf iyo boodh; qaylo iyo dhaqdhaqaaqa loo gudbiyay dhismaha; is dhexgalka dabiiciga ah ee leh ducts meshed (turbinada waaweyni waxay dilaan tirakoob lagu qiyaasay 140,000 ilaa 328,000 shimbiraha sanad kasta Mareykanka (Loss, Will iyo Marra, 2013); dhismayaasha muraayadaha ayaa dilay 365 ilaa 988 milyan (Loss et al., 2014); cidna ma laha macluumaad loogu talagalay modules-dhexdhexaad ah).

Maxaa la doonayo in ay run tahay

Si ay u taaj on windy 6.5 m / s goobta, qiimaha korontada ku xiran tahay laba wax oo aan ka shaqeyn kartaa: sida xoog badan oo mitir kasta oo laba jibbaaran ee dhul frontal bixiyaa, iyo waxa uu ku kacayaa la rakibay.

Cp ee gobolka hore	$300 m² kasta	$500 m² kasta	$800 m² kasta	$1,100 mitir laba jibbaaran
0.15	$0.24	$0.40	$0.63	$0.87
0.20	$0.18	$0.30	$0.47	$0.65
0.25	$0.14	$0.24	$0.38	$0.52
0.30	$0.12	$0.20	$0.32	$0.43

Meel ay ku guuleysan karaan, iyo meesha ayna

Waxay ku guuleysan kartaa:

• Windy dhismayaasha waaweyn iyo goobaha xeebta, sida ku xigta qorraxda: dabaysha ee derbiga xagga sare ee habeenkii, xilliga jiilaalka iyo roobab, marka ay panels qorraxda soo saaraan wax yar.
• Saqafka horeyba buuxa ama shaashadda. A taajku wuxuu isticmaalaa cidhifka, ma aha dhul saqafka ah, mana la tartami karo panels, beerta ama terraces.
• Off-grid awooda halkaas oo cables waa qiimo jaban: sensors, iftiinka, qalabka telecom, xarumaha cimilada ee jidka, mast iyo dhismayaasha xeebta.
• Baararka horey u jira: xayiraadaha shilalka waddooyinka iyo tareenka, darbiyada badda iyo parapets-ka jidka, halkaas oo dhismaha loo bixiyo.
• Dhis iyo waxbarashada. A taaj oo kale ah in ay noqoto waa warbixinta dadweynaha a panel qorraxda ma aha; iskuulada, musea iyo dhismayaasha taariikhiga ah qiimaha in.

Ma guuleysan karo:

• Sida macdanta qiimaha jaban ee tamarta. Beero waaweyn oo hawada iyo qorraxda ah waxay ku kacayaan $0.04 to $0.10 per kWh; waxba ma aha dhisme u dhow.
• In waddooyinka magaalada la ilaaliyo iyo degmooyinka hoose ee hoos yimaada, halkaas oo dabaysha dhexdhexaadka ah ay ka hooseyso 4 ilaa 5 m / s dhererka saqafka.
• Flat on a facade. Si kastaba ha ahaatee, rotors waa la naqshadeeyay, derbiga xiran ma laha socodka.

Fase 0 ilaa 3 u baahan tahay in ka badan $220,000 to $430,000 iyo laba sano. Qayb kasta oo ka mid ah waxay leedahay meel joojin cad: haddii jidka hawada ma muujin Cp hordhac ah oo ku dhow 0.2 in a array, waxaan joojin doonaa halkaas iyo daabacaadda sababta.

Cidda aan u baahanahay

• Aerodynamicist leh yar-Reynolds iyo ducted-rotor khibrad, si ay u naqshadeeyaan oo dib u eegista daboolka, duct iyo stator.

• Mashiinka saaxiibka in injection molding ama rotomoulding si ay u qiimeeyaan daboolida iyo ducts at tirada.

Fikrad wanaagsan ayaa la soo dhaweynayaa

The Fan Wall waa jawaabta su’aal ka weyn: sida ay u yihiin meelaha dadka deggan hadda samayn, kaydin ama badbaadin awood nadiif ah in ka badan sida ay maanta? Haddii tirada ku qoran boggaan ay kugu qanciyaan in hab kale oo wax lagu qaban lahaa, waxaannu doonaynaa inaan kuu sheegno. Rooftop qorraxda oo sidoo kale ka dhigaysa kulaylka, kaydinta kulul, dhaqaale laga soo kabsaday biyaha muhiimka ah, kuleylka wasakhda ama smarter waqtiga dalabka dhammaantood waxay ku guuleysan karaan taaj dabaysha ee dhismayaal badan. The idea radar waxay la barbar dhigtaa iyaga, iyo mid kasta oo ka mid ah wuxuu leeyahay maqaalkiisa oo la qoray si daacadnimo ah oo aan halkan u adeegsanno.

Qaar ka mid ah xubnaha Foundation waxay yeelan karaan xiriiro oo maqli kara pitch. Si loo soo bandhigo, fikrad u baahan tahay shaqo, qaab nolosha dhabta ah oo si dhab ah awoodda u soo saarta, iyadoo natiijada lagu miisaamo qalab, aan la sheegin; taas waa sababta saxda ah ee boggani ku dhammaado jidka hawada iyo diyaaradda daaqadda ka badan sawir. Fikradaha buugaagta waa la soo dhaweynayaa: haddii ay physics iyo tirada yihiin xoog leh, waxaan ku daabacan kartaa halkan bogga internetka. Laakiin kor u qaadista maalgashiga aan qaabka shaqada waa aad u adag, iyo waxba halkan ma aha ballan ah oo lacag, soo noqnoqda ama soo bandhigida. Qiimaha waa mid ka mid ah boggaan isku dayaya inuu la kulmo: muujiya tirada, sheeg waxa ay ku tusin lahaa inaad khalad tahay, iyo soo jeedinta imtixaan cheapest.

Sideed u caawin kartaa

• La soo bandhigo aqoontaada. Haddii aad ka shaqeyso mid ka mid ah qaybaha kor ku xusan, isku day inaad shaqo bixiso. Inkasta oo saacad dib u eegista qaabkeena waa qiimo badan.
• Offer a roof windy. A dhisme dheer oo ku yaal xeebta, buur ama dhulka furan oo leh si ay u helaan daaqadda ammaan ah ayaa martigelin kara diyaaradda. Nagu sheeg meesha ay tahay iyo sida dabayshu caadi ahaan u dhacday.
• Share xogta dabaysha. Sanad ah oo dabayl tirakoobka ka saqafka, jidka ama masto xeebeed noo caawiya in ay doortaan goobta pilot.
• Ka eeg xisaabtayada. Model waa furan yahay. Haddii aad aragto qalad, noo sheeg: waxaan ka dooran lahaa in la hagaajiyo hadda ka hor kadib darawal.
• U soo bandhig fikrad wanaagsan. U dir iyada oo loo marayo qayb ka mid ah foomka la dhibaatada ay xalliso, tijaabada physics, qiimaha ku dhow per kWh iyo imtixaanka ugu raqiisan ee ay u suurtogal tahay in ay been abuurto.
