I-Fan Wall

Yonke i-turbine yomoya okubonayo ilandela lo mqondo: isivinini esisodwa esikhulu kunalokho okunokwenzeka, esiphezulu kunalokho okunokwenzeka. Isebenza kahle, futhi idinga ama-cranes, indawo evulekile kanye neminyaka yezimvume. Isiphakamiso sethu siyilokho okuphikisanayo. Ingabe ama-rotors ancane, afakwe endaweni lapho imiphakathi ikhona khona, angakhiqiza ugesi ngentengo efanele? I-Fan Wall ideskithophu yasungulwa ekuqaleni ngaphakathi kwe Local Solar System Foundation ngo-2020; le khasi yimodeli yayo evulekile, evuselelwe.

Le khasi libhalwe abantu abazoxhasa, bathuthukise noma bavavanye imibono. Kuyinto eyenziwe ngokwezifiso hhayi i-brochure yokuthengisa. Siqhube inani lethu lokuqala lokwakha, sathola lapho lihlulekile khona, siphinde sayilayisha futhi saqhuba inani futhi. Uhlobo oluncane: idonga lekhompyutha elinomoya ku-facade alisebenzi, i-crown ye-rotors enkulu efakwe umbhoshongo engxenyeni yesikhala esibandayo ingakwenza ugesi ongempela, futhi ngeke inqobe amapaneli kalanga ngentengo ngaphandle kokuthi izinto eziningi sikwazi ukuzihlola ziphume kahle. Yonke inombolo ngaphansi ivela kwimodeli yethu evulekile (code, data).

Uhlobo 1, nokuthi kungani asebenza

Imibono yokuqala yayiyisakhiwo esingaphambili, 40 m eside ne-15 floors ephezulu, efakwe cishe ama-110,000 ama-fans we-120 mm, wonke ahamba emuva ukuze imoto yakhe ibe yi-generator. Isithombe esihle. Kuhluleke ngenxa yezizathu ezintathu, ngokulandelana kokuzibophezela.

**1. Umoya awukwazi ukudlula emgodini ovalekayo. ** I-turbine ithatha amandla omoya osuka emoya ohamba ngayo. Ku-facade eqinile umoya uvala (abanjiniyela bayibiza ngokuthi ukuvalwa) futhi ihamba phezulu, ngezansi kanye ngakwesobunxele. Uma ngabe wonke umqambi unesikhala esingu-30 cm ngasemva, evulekile emaphethelweni naphezulu, ukuqhubeka kwenza isiphetho esinzima: yonke umoya ophuma ku-1,800 m² we-fan kufanele ushiye nge-39 m² yesikhala, ngakho kungadlula ama-fan angaphezu kuka-2.2% wejubane lomoya. Umandla uhamba ne-cube yejubane, ngakho idonga lizogcina kahle ngaphansi kuka-0.01% kwento abadlali abafanayo bazoyenza behlala mahhala. Ukulinganiselwa kwecala elingaphakathi kokufakwa okune-ventilator kungenxa yokuthi: 0.2 kuya ku-0.6 m/s yomoya osuka ekamelweni udlula emkhathini ngejubane le-5 m/s (Salonvaara et al., 2007). Guqula imodeli engu-3D ngasentshonalanga kuhlobo 1 ukuze uyibone: ama-streaks omoya ayeka edonga bese ehamba.

**2. Izinhlamvu ezincane zisebenza kabi. ** I-120 mm fan blade inentambo engaphezu kuka-2 cm. Umoya ojikelezayo uhamba ngenombolo yeReynolds engaphansi kuka-10,000, imithetho lapho amaphiko alahlekelwa khona ingxenye enkulu yokuphakama-ku-ukudonsa: izindiza ezilula zithuthukisa “ngaphezu kohlelo lwesibalo” ngaphezulu kwenombolo ebalulekile yeReynolds eyi-70,000 (Lissaman, 1983). I-turbines elinganiselwa ngesentimitha ifinyelela amandla alinganayo angama-9% (Howey, Bansal noHolmes, 2011); i-rotor yekhompyutha engu-10 cm esetshenziswa njenge-turbine yanikeza u-28 mW ku-5 m/s, cishe ama-4% wekhono lemvula ngaleyo ndlela ngokulinganisa kwethu (Federspiel noChen, 2003). Ama-fan wekhompyutha akhiwa ukuze acindezele umoya, hhayi ukuba acindezelwe ngawo.

**3. Amawaka amancane ama-generator alahlekelwa yinto encane abayenzayo. ** Imoto yefan enikeza inhlanganisela ye-watt ku-volts ambalwa ingalahlekelwa yi-10 kuya ku-40% kwi-diode rectifier yinye. Silinganisela ukuthi isilinganiso sethu sokuqala esingu-54% sizosetshenziswa kunoma iyiphi inqwaba esuka kwifan kuya ku-grid.

Nakuba ungazitholi isizathu sokuqala ngokuphelele (i-wall evulekile ye-fans), inguqulo 1 izobiza cishe $4.20 per kWh on a windy coast and $18 in a city, ezimashumi amabili kuya kwezinkulungwane izikhathi zentengo ye-rooftop solar.

I-physics emisa amaphesenti

Umandla othwaliwe ngumoya ngendawo A yi P = ½ ρ A v³, nobukhulu bezulu ρ = 1.225 kg/m³. I-cube iyinto yonke: ku-6 m/s imitha yesikwere ithatha u-132 W, ku-12 m/s 1,058 W. Izinga eliphakathi leminyaka, isakhiwo sedolobhana eline-4 m/s inkungu ephakathi nendawo sinikeza cishe 75 W ngayinye m²; isiqhingi esivulekile esingu-6.5 m/s mayelana 321 W ngomfutho ofanayo.

Akukho siphequluli esikhethiwe. Akukho mshini ovulekile ongakhishwa ngaphezulu 16/27 ≈ 59.3% ye amandla edlula ingxenye yayo, ngoba umoya kufanele uqhubeke nokuhamba ngaphandle kwendlela.

Into eyisithupha esijikelezayo esingayifaka. Izijikelezo ezimbili ezihamba phambili (njengezigaba zenjini ye-jet) zingafinyelela kungaphezu kuka-16/25 = 64% wokusebenza ngendawo eyodwa yesijikelezo, futhi ziningi kakhulu kuphela 2/3 (Newman, 1986). Injini ye-jet iqoqa izigaba ngoba icindezela umoya ngengxenye encane eqinile enesimo esihlukile sokushisa uphethiloli. Umoya okhululekile awunikezanga lo mthwalo: isikhashana ngasinye esingeziwe sihamba kancane umoya, futhi umoya ohamba kancane uphuma ngaphakathi kwedivayisi. Ukufinyelela okulinganiselwe kwe-rotors yezulu ejikelezayo isuka ku-0 kuya ku-60%, kodwa ukuhlolwa okulawulwa kahle kutshalwe ku 2 kuya ku-10% (Adema et al., 2026 review).

Into eyenza ama-vanes we-stator akhuphuke. I-rotor ishiya umoya ujikeleza, futhi ujikelezo lulahlekelwa amandla. Ku-low tip-speed ratios of small rotors the loss is large: the ideal Glauert rotor reaches 0.42 at a tip-speed ratio of 1, 0.51 at 2 and 0.57 at 5. Izibhamu eziqinile ezingaphansi kwe-rotor zingathola ingxenye yazo. Akukho muntu olinganisele lokhu ku-turbine yomoya; ezindaweni zokushayela izindiza, lezi zibhamu zanikeza 2 kuya ku-5% (Li et al., 2017).

Into engenza i-duct ikhuphuke. I-duct enesibhakabhaka esincane (i-”wind lens” ye-Kyushu University) iphansi umthwalo ongaphansi kwe-rotor futhi isusa umoya ongaphezulu ngaleyo ndlela. Kuzifundo ze-wind-tunnel, i-compact brimmed diffuser yakhuphula amandla okusebenza kusuka ku-0.37 we-rotor emnyama kuya phakathi kuka-0.7 no-0.88, ngokuphathelene nendawo ye-rotor, kodwa kuphela ku-0.48 kuye ku-0.54 ngokuphathelene ne-brim ephelele (Ohya and Karasudani, 2010). Lokhu kuyinkinga: ngemitha eyisikwere yendawo engaphambili, ama-ducts angeke adlule umkhawulo weBetz, “ngokusebenza kwezinto zokuthuthukisa amandla eziphezulu kuka-3 azizange zifinyelelwe”, futhi izinjini ezixhunywe zineminyaka engu-50. Kuze kube manje ngaphandle kwempumelelo yokuthengiswayo” (van Bussel, 2007). Uhlelo olusha olubiza kakhulu, iFloDesign/Ogin, lwasusa izimoto zayo zamandla eminyakeni emihlanu futhi lwavalwa ngo-2017 (I-Gipe, 2017).

Isayizi ibalulekile ngenxa yenombolo kaReynolds. Sibala isivinini esingcono kakhulu esisikhona kunoma iyiphi ubukhulu ngemodeli yomoya we-blade-element (umphumela ongcono kaGlauert ngokuhamba kwe-wake, incazelo nezinkinga ze-hub, kanye nokuphakama-ku-ukudonsa umlinganiso owela ngenombolo kaReynolds, kusuka kuma-airfoils aphansi e-Reynolds alinganiselwe njenge Selig’s SG6043):

Ubukhulu be-rotor	Ama-blades, isilinganiso sejubane lokususa	Inani likaReynolds (75% umkhawulo)	Uhlobo oluhle kakhulu lwe-Cp
4 cm	8, 1.25	4,500	0.23
12 cm (ikhompyutha fan)	8, 1.5	12,000	0.29
25 cm	8, 2.0	20,000	0.36
50 cm (iyunithi ethuthukisiwe)	6 kuya ku-7, 2.5	43,000	0.39 kuya ku-0.40
1 m	6, 3.0	74,000	0.42
7 m (i-turbine encane)	8, 4.5	265,000	0.49

Lawa ama-ceilings asetshenziselwa izibhamu ezifakwe ngenhloso, ngaphambi kokulimala kweqiniso. Njenge-check, i-turbine ephathekayo engu-39 cm eyenziwe ngokwenhloso ilinganiselwe ku-0.32, lapho imodeli yethu inikeza khona u-0.39 kulo bukhulu (Kishore, Coudron and Priya, 2013): ngakho-ke sicabanga ukuthi ihardware yokuqala ifinyelela ku-65 kuya ku-90% yexabiso le-design, futhi inciphisa kakhulu ama-rotors wesentimitha, lapho ukuhlukaniswa kwe-laminar kudonsa khona.

Indlela yomoya. Ingxenye eqinile isebenzisa kuphela ingxenye yomoya ophuma kuyo. Umandla uphansi ngokuyisisekelo nge-cube ye-engile yokungalingani kwe-rotors evulekile futhi ngokucophelela kakhulu kuma-ducts (Tamaro et al., 2024; Richmond-Navarro et al., 2022). Ngemoya ophakathi nendawo onamandla, iyunithi ebhekene nayo igcina cishe 47% ye-energy i-rotor ehlala ilungele izothola. Uhlobo 1 luthathelwe 100%.

Uhlelo oluthuthukisiwe: igolide engxenyeni yesitezi esibheke umoya

Thola konke okuphezulu futhi ukwakheka kuncane kakhulu: ama-rotors amakhulu lapho inani le-Reynolds lincane, ezingeni elivikelayo nelingasheshisa, lihlala likhululekile lapho umoya ungadlula khona, libhekene nomoya okhona endaweni esitezi lapho ukukhishwa kunamandla. Le ndawo iyingxenye yesitezi. Umoya ohlasela isakhiwo unyuka futhi ujikeleza phezu kwengxenye; ngaphezu kwengxenye yesitezi esiphezulu sezulu, umoya usuka ku-1.06 kuya ku-1.25 izikhathi zejubane ephakeme lesitezi, kodwa kuphela ama-0.38 izikhathi lapho ingxenye iphansi (Mertens, 2006).

Ingxenye ngayinye iyisikwere esingu-725 mm: i-0.5 m ye-blade eyisithupha yomshini ojikelezayo egumbini elincane lelanga, amabhande amane we-stator avuselela ezinye izimo zokujikeleza futhi athwale i-generator engu-50 kuya ku-300 W, i-mesh yokugqugquzela engangeni manzi kanye nebhodi elilodwa lokusebenza eliqinile nokulandela umkhondo wokukhanya okuphezulu. Ama-rowes amabili akwenza i-1.45 m ubude be-crown ku-steel rails ngaphesheya kwe-parapet. Umntu ngamunye angaphakamisa iyunithi bese eshintshana nayo.

Ama-blades angeke aqondwe. Imodeli ihlela ukuthi babone inani le-Reynolds, cishe ama-45,000 ku-6 m/s: ukusakaza 62 mm eduze kwesisekelo esincane ukuya ku-36 mm engxenyeni, ukuguqulwa kusuka ku-38 ° kuya ku-10 °, ukwakheka kwesilinganiso se-speed-speed se-2.5. Ku-6 m/s i-rotor ijikeleza ku-700 rpm; amathuluzi ayo ahamba ngama-30 m/s emoya we-10 m/s, ngaphantsi kwengxenye yamathuluzi angama-79 m/s we-turbine enkulu.

Amanani athembekile

Imitha ngayinye yesikwere sendawo engaphambili yindlela efanele yokuqhathaniswa: i-facade, insimu yendlu kanye nesihlalo sokuhamba ngezinyawo zonke zidlala indima efanayo, indawo ebhekene nomoya. Amaxabiso aphakathi, ngezinga eligcwele le-pessimistic-to-optimistic ku imodeli yedatha. Ugesi ufaka phakathi indlela yomoya, ukungqubuzana (ukulahlekelwa kuka-5 kuya ku-15%) nokutholakala (92 kuya ku-97%). Izindleko ze-energy: iminyaka engu-20 ngesilinganiso esingu-7% sentengo ephansi, ukunakekelwa 2 kuya ku-5% yemali engenayo ngonyaka.

Ithebula lithi:

• I-duct ithola indawo yayo, nje. Nge frontal m², amamodyuli axhunywe (B) ashaya ama-rotors afanayo evulekile (B0) ngamaphesenti angama-10 kuya ku-30%, ikakhulukazi ngoba bamelana nesimo sezulu kahle. Banikeza futhi umphathi, incazelo encane kakhulu kanye nendawo ye-stator.
• Isijikelezisi sesibili asikhokhi. Sifaka cishe i-6% ye-energy nge-16% engaphezulu kwezindleko. I-jet-engine-style multi-stage wind module iphele ngephysics, hhayi ngokufisa.
• Izingxenye ezihamba ngezulu kuphela ezikhokha. I-crown yonke ejikeleze isikhala ithola kuphela u-55% ngayinye ye-module uma kuqhathaniswa nengxenye ehamba ngezulu kuphela, ngoba ezinye izingxenye zibheke kude nomoya okhona isikhathi esiningi. Kulesi sakhiwo sethu esibhekiswe kuso (40 × 20 m, 45 m ubude) i-crown efanelekayo yingxenye yomoya kuphela: 60 m², cishe ama- $ 64,000, mayelana ne-9,500 kWh ngonyaka kusayithi elinamanzi, 2,600 edolobhaneni. Imali efanayo esitezi sokukhanya kwelanga ithenga cishe amapaneli angama-155 m² akhiqiza cishe ama-35,000 kWh ngonyaka.
• Ezindaweni eziphakathi akukwazi ukuncintisana. Umoya ophansi ofakwe ezindaweni zokwakha unerekhodi elibi: ama-turbines angama-26 eWarwick Wind Trials afinyelele ku-0.85% wezinga lokumelana (Encraft, 2009), futhi ama-turbines amathathu eLondon’s Strata tower amiswa ngemuva kokukhathazeka ngezingcingo nezingcindezi.

Uhlelo lwe-US Small Wind Fleet lulinganiselwa ku-14 kuya ku-16% $6,680 to $9,630 nge-kW efakwe ngo-2024 no-2025 (I-PNNL idlulisa izibikezelo zezulu). I-crown yethu iwela ku- $ 6,300 nge-kW elinganiselwe, engxenyeni efanayo, okuyiphawu lokuthi inani elilinganiselwayo alifani nephupho.

Okusho ukuthi, i-

Iqinisekisiwe (incwadi yemfundo noma ilinganiselwe): amandla omoya kanye ne-Betz limit; isikhala esingu-16/25 se-rotors ezimbili; ukuthi ama-ducts akhuphula amandla ngayinye indawo ye-rotor kodwa hhayi ngaphezulu kwe-Betz ngayinye indawo engaphambili; ukuthi ama-blades amancane ku-Reynolds amanani angaphansi kuka-70,000 alahlekelwa umphumela; ukuthi umgwaqo ovalekayo awunakudlula; ukuthi izindonga zikhawulela ukukhishwa kwe-upwind; ukuthi izakhiwo ezifakwe kuma-micro turbines emigwaqweni zisebenza kabi.

Ingase ibe khona (ixhaswe, kodwa ayilinganiswe kule nqubo): i-rotor engu-0.5 m eyenziwe ngeReynolds 45,000 efinyelela kumandla alinganayo angu-0.3 kanye no-0.55 endaweni ye-rotor esitezi esincane se-duct; 75% ukunemba kwe-chain kusuka ku-rotor kuya kwi-grid ngo-50 kuye ku-300 W generators ne-module-level MPPT; izindleko ezifakwe zingaphansi kuka-$1,000 ngom² wephrojekthi yokuqala.

Izibalo (kudingeka zilinganiselwe): ukuthi inani lezintambo ezifakwe ngakwesobunxele nesokudla lilahlekelwa yiliphi elinye (sicabanga ukuthi 10 kuya ku-30%); ukukhawulelwa kweqiniso nokugqwala ekhoneni lesakhiwo esinikeziwe; ukuhlala isikhathi eside kwamawaka amabhethri eminyakeni eyi-20 yezingcindezi, ikhephu kanye nothuli; umsindo kanye nokugqwala okudluliselwa ngaphakathi kwesakhiwo; ukungqubuzana kwezilwane eziphilayo nezintambo ezixhunywe ngemesh (izintambo ezinkulu zibulala izinhlanzi ezingu-140,000 kuya ku-328,000 ngonyaka e-US (Loss, Will and Marra, 2013); izindlu zeglasi zibulala amazigidi ezingama-365 kuya ku-988 (Loss et al., 2014); akukho muntu onedatha yezintambo ezixhunywe ngesikhala sesitezi).

Yini efanele ibe yiqiniso

Imali yogesi esitezi esiphezulu sesitezi esihamba nge-6.5 m/s, izindleko zombane zixhomekeka ezingeni lezinto ezimbili esingazisebenza kuzo: ukuthi amandla aphi okwenziwa yimitha ngayinye yesikwere sendawo engaphambili, nokuthi kubiza malini ukufakelwa.

Cp endaweni engaphambili	$300 nge-m²	$500 nge-m²	$800 nge-m²	$1,100 nge-m²

lapho ingawina khona, futhi lapho ingakwazi khona

Ingawina:

• Izindlu eziphakeme ezinomsindo kanye nezizinda zesihlabathi, njengengxenye yelanga: umsindo esitezi esiphezulu se-spikes ngehora, ngobusika nangemkhathini, lapho amapaneli elanga akhiqiza khona kancane.
• Izinsimu zigcwele noma zimnyama. I-crown isebenzisa umkhawulo, hhayi indawo yensimu, futhi ayincintisana nezindawo zokudweba, izitshalo noma ama-terraces.
• Ugesi ongaxhunyiwe ku-grid lapho amakhebula ebiza kakhulu: izibonisi, ukushayela, imishini yezokuxhumana, izikhumulo zezulu ezisitezi, amamasti kanye nezindlu ezisenyakatho.
• Amaphakethe akhona: amaphakethe emoto kanye ne-railway, amadonga olwandle namabhuloho, lapho isakhiwo sikhokhelwa khona.
• Ukubona nokufundiswa. Ikhanda elijikelezayo liveza ukuthi iphaneli yelanga ayinjalo; izikole, ama-museums namasakhiwo aphawulekayo akholelwa kulo.

Ingawina:

• Isizinda esibizayo sokukhiqiza ugesi. Izindawo ezinkulu zokutshala umoya nelanga zibiza i-$0.04 to $0.10 nge-kWh; akukho okunye okutholakalayo esitezi esiphansi.
• Ezindaweni ezishisayo zedolobha kanye nezifunda eziphansi, lapho umfutho womoya ophakathi nendawo ungaphansi kuka-4 kuya ku-5 m/s esitezi esiphezulu.
• Isikhala esivulekile ebusweni. Noma kunjalo, ama-rotors afakwe kahle, idonga elivalayo alinalutho lokudlula.

Imibono engcono iwelkoma

I-Fan Wall iyisinqumo esisodwa sombuzo obanzi: kanjani ukuthi izindawo lapho abantu behlala khona zingakwenza, zigcine noma zilondoloze amandla ahlanzekile kunalokho abakwenzayo manje? Uma inani lekhasi likuqinisa ukuthi indlela ehlukile izosebenza kahle, sifuna ukulilalela. Ilanga lesitezi esiphezulu elikhiqiza ukushisa, indawo yokugcinwa kwe-thermal, ugesi obuyiselwe kusuka emigodini yamanzi, ukushisa okulahlekile noma ukuhlela isikhathi sokufuna ngokuzimela kuzo zonke zingalimaza ikhanda lomoya ezindlini eziningi. I imibono ye-radar iqhathaniswa nazo, futhi ngayinye inesihloko sayo esibhalwe ngokuvumelana okufanayo sisebenzisa lapha.

Abanye amalungu e-Foundation bangaba nezingxoxo nabantu abakwazi ukulalela isinqumo. Ukubekwa, imibono idinga umsebenzi, imodeli yokuphila engokoqobo ekhiqiza amandla, nemiphumela yayo elinganiselwe kuthuluzi, hhayi ukubhekwa; lokho kuyisizathu esicacile sokuthi kungani lekhasi liphela nge-wind tunnel ne-rooftop pilot ngaphezu kokwenza. Imibono yephepha ivunyelwe: uma uphysics namanombolo aqinile, singazishicilela lapha kwiwebhusayithi. Kodwa ukuqoqa imali engenayo ngaphandle kwemodeli esebenza kahle kunzima kakhulu, futhi akukho okuzobe kungenxa yokuhlinzekwa ngemali, ukubuyiswa noma ukungeniswa. Isilinganiselwa yisona lesi khasi sizama ukuhlangabezana: bonisa inani, sithi yini ekhombisa ukuthi ukhohliwe, futhi uphakamise isivivinyo esibiza kakhulu.

Ungasiza kanjani

• Bhekisa ubuhlakani bakho. Uma usebenza kunoma yiliphi izwe elingezansi, nikeze umsebenzi. Nakuba ihora ukuhlola imodeli yethu kuyinto ebalulekile.
• Inikeza isikhala esibandayo. Isakhiwo esiphakeme elwandle, emfuleni noma ezindaweni ezivulekile ezinesikhala esiphephile sokufinyelela kungasiza umgibeli. Sitshele ukuthi ikhona kuphi futhi indlela omoya ehamba ngayo.
• Hlanganisa idatha yezulu. Unyaka wokuhlola izulu kusuka esitezi, emgodini noma ezindaweni eziphakathi nendawo usiza ukukhetha indawo yokuhlola.
• Hlola i-math yethu. I imodeli iyavuliwa. Uma uthola iphutha, sithi: sifuna ukuxazululwa manje kunalokho ngemuva kokuhlola.
• Ingaba nemibono engcono. Ithunyelwe ngefomu le-iminikelo kanye nenkinga exazululwe, ukuhlolwa kwephysics, izindleko ezincane ngayinye ye-kWh nokuhlolwa okuphansi okungabonisa ukuthi kuyiphutha.
