The Fan Wall

Pamenepo, magetsi onse a mphepo omwe mwawona amatsatira logic yomweyo: rotor imodzi yolimba kwambiri komanso yotsika kwambiri. Amagwira ntchito molimba mtima, ndipo amafuna ma crane, dziko lotsegulidwa ndi zaka za zilolezo. Funso lathu ndi losiyana. Kodi zingatheke kuti ma rotors ochepa, omwe amapangidwa m’madera omwe mizinda yakhala ikupezeka, atenge mphamvu pa mtengo womwe umatanthauza?

Izi tsamba ndi yolemba kwa anthu amene angagwiritse ntchito ndalama, kukhazikitsa kapena kuyesa mfundo. Sichiyenera kuonedwa kuti ndi buku la malonda. Tidayendetsa mayunitsi a mtundu wathu woyamba, tinapeza komwe kumalephera, kusinthidwa, ndikusinthanso mayunitsi. M’mawu ofupi: mkuwa wa mafani a kompyuta pa facade sangakhale ntchito, korona ya ma rotors akuluakulu omwe amadutsa pa khoma la mphepo amatha kupanga mphamvu yoyenera, ndipo sizingakhudze mapaneli a dzuwa pa mtengo ngati zinthu zingapo titha kuyesa bwino. Nthawi zonse pansipa timachokera ku model yathu yotsegulira (code, data).

Version 1, ndi chifukwa chake sichigwira ntchito

The first idea was a building facade, 40 m long and 15 floors high, covered in about 110,000 fans of 120 mm, each run backwards so its motor becomes a generator. Ndi chithunzi chabwino. Zimalephera chifukwa cha zinthu zitatu, m’njira yoyenera.

**1. Air sangathe kupita mwa msewu wotseka. ** A turbine amatenga mphamvu kuchokera ku mpweya womwe umayenda mwake. Pa facade yolimba, upepo umatha (opanga amatchedwa stagnation) ndipo amayenda pamwamba, pansi ndi kumbuyo. Ngakhale kuti panthawiyo, ma fanizo onse anali ndi 30 cm yopanda madzi m’mbali mwake, yotsegulidwa kumbuyo ndi pamwamba, kugwirizana kwa zinthu kumaika malire ovuta: zonse zakumwa zamadzi zomwe zimalowa m’ma 1,800 m² a ma fanizo ziyenera kupita m’malo opanda madzi pafupifupi 39 m², motero zingathe kutuluka m’ma fanizo popanda kupitilira 2.2% ya mphamvu ya upepo. Power goes with the cube of speed, so the wall would keep well under 0.01% of what the same fans would make standing free. Kuwerengera kwa mpweya wotentha wamkati kumagwirizana ndi: 0.2 mpaka 0.6 m / s ya kutuluka kwa mpweya wa cavity mu mphepo ya mpaka 5 m / s (Salonvaara et al., 2007). Sungani 3D model pamwamba pa mtundu 1 kuti muone: ma wind streaks amathamanga kumbali ya msewu ndi kutuluka.

.

**2. Mapepala ang’onoang’ono amagwira ntchito mosayenera. ** Pepala la fan lokhala ndi 120 mm lili ndi chombo cha pafupifupi 2 cm. Mphamvu ya mpweya yomwe imayenda m’malo mwake imapita ku Reynolds number yokwana 10,000, njira yomwe mawings amawononga kwambiri kuchuluka kwa lift-to-drag ratio: ma airfoils osalala amasintha “kuposa lamulo la kukula” pamwamba pa Reynolds number ya pafupifupi 70,000 (Lissaman, 1983). Ma turbines ochuluka a masentimita amafika pa mphamvu zopitilira 9% (Howey, Bansal ndi Holmes, 2011); a 10 cm kompyuta-fan rotor ntchito monga turbine anatumiza 28 mW pa 5 m / s, za 4% ya mphamvu ya upepo kudzera mu kafukufuku wathu (Federspiel ndi Chen, 2003). Ma fanizo a kompyuta amapangidwa kuti azithamanga pamadzi, osati kuti azithamanga.

**3. Mamiliyoni a ma generators ang’onoang’ono amawononga zomwe zimapanga. ** Mota ya fan yomwe imapatsa gawo la watt pa volts angapo ingapeze 10 mpaka 40% mu diode rectifier yokha. Tikukhulupirira kuti 54% ya magalimoto onse omwe amayenda kuchokera ku fan kupita ku gridi ndi ochokera ku China.

Ngakhale kunyalanyaza chifukwa choyamba chonse (a free-kukhazikika m’mphepete mwa okonda), mtundu 1 ndi mtengo wa pafupifupi $4.20 per kWh on a windy coast and $18 mu mzinda, makumi awiri mpaka mamiliyoni ambirimbiri mtengo wa rooftop dzuwa.

Fiziki yomwe imayika mipaka

Kuwala kwa dzuwa A ndi P = ½ ρ A v³, ndi kulemera kwa madzi ρ = 1.225 kg/m³. Kuwunika kwa kuzungulira kumatanthauza zonse: pa 6 m / s mita imodzi yaying’ono imathamanga 132 W, pa 12 m / s 1.058 W. Kuphatikiza pa chaka chimodzi, nyumba ya mzinda ndi 4 m / s yotentha imapatsa pafupifupi 75 W pa m²; kuwala kwakum’mawa kwa 6.5 m / s za 321 W pa m².

Betz limit. No otsegulira rotor angagwiritse ntchito zambiri kuposa 16/27 ≈ 59.3% ya mphamvu yoyenda mwa malo ake, chifukwa mpweya ayenera kutsatira kunyamula kuchokera panjira.

Kodi yachiwiri rotor angawonjezera. Ma rotors awiri m’gulu (monga ma stages a injini ya jet) amatha kufika panthawi yochuluka 16/25 = 64% ya mphamvu mwa malo a rotor imodzi, ndi infinitely ambiri okha 2/3 (Newman, 1986). Jet injini stacks ndondomeko chifukwa imangotulutsa mpweya mwa chitoliro chokhala ndi kuwala kwakukulu kuchokera ku mafuta otentha. Free upepo amapereka palibe monga kukana: iliyonse yapadera gawo amalepheretsa mpweya m’tsogolo, ndi slow air kumatuluka pafupi chipangizo. Kuwonjezeka kwamagetsi osinthira mpweya kumachokera ku 0 mpaka 60%, koma kuyesa koyambirira komwe kumayesedwa bwino kumapezeka pa 2 mpaka 10% (Adema et al., 2026 review).

Kodi stator vanes angawonjezera. A rotor amasiya mpweya wozungulira, ndipo swirl ndi mphamvu yowonongeka. Pa ma ratios otsika a tip-speed a rotors ochepa kuwonongeka ndi kwakukulu: rotor yoyenera ya Glauert imafika pa 0.42 pa ratio ya tip-speed ya 1, 0.51 pa 2 ndi 0.57 pa 5. Kusintha kwa magazi m’mimba kumatha kuyambitsa matenda ena. Palibe amene wawerengera izi pa turbine yamphamvu ya mphepo; pa ndege zoyendetsa ma propeller monga vanes anapatsa 2 mpaka 5% (Li et al., 2017).

Zinthu zomwe duct ingawonjezere. duct ndi chingwe chopanda kanthu (“woyendetsa mpweya” wa Kyushu University) amachepetsa kupweteka kwamkati mwa rotor ndikutulutsa mpweya wowonjezera. Panthawi yoyeserera ya mpweya wa mpweya, diffuser yokhala ndi chingwe cholimba chidawonjezeka ku mphamvu yamagetsi kuchokera pa 0.37 kwa rotor yopanda malire mpaka pakati pa 0.7 ndi 0.88, poyerekeza ndi malo a rotor, koma mpaka 0.48 mpaka 0.54 poyerekeza ndi khoma lonse (Ohya ndi Karasudani, 2010). Izi ndi zosatheka: pa mita imodzi ya frontal, ma ducts sanathe kuwononga Betz limit, “mu ntchito yogwiritsira ntchito mphamvu zowonjezerapo za 3 sizingathe kukwaniritsidwa”, ndipo ducted turbines ana “zaka zoposa 50”. Komabe, palibe chitsimikizo chokwanira kuti “(van Bussel, 2007). Kuyesa koyambirira kwaposachedwa, FloDesign / Ogin, idachotsa ma turbines ake m’masabata asanu ndi awiri ndipo idatulutsidwa mu 2017 (Gipe, 2017).

Kukula kwa zinthu chifukwa cha Reynolds mndandanda. Tidawerengera rotor yabwino kwambiri pamtundu uliwonse ndi mtundu wa blade-element momentum (Glauert’s optimum ndi kuzungulira kwa wake, tip ndi kuwonongeka kwa hub, komanso kuchuluka kwa lift-to-drag komwe kumagwa ndi Reynolds number, kuchokera ku ma airfoils otsika a Reynolds monga Selig’s SG6043):

Rotor m’lifupi	Mapepala, kulumikizana kwa ma speed	Reynolds mndandanda (75% radius)	Best kupanga CP
4 cm	8, 1.25	4,500	0.23
12 cm (computer fan)	8, 1.5	12,000	0.29
25 cm	8, 2.0	20,000	0.36
50 cm (module yosinthidwa)	6 mpaka 7, 2.5	43,000	0.39 mpaka 0.40
1 m	6, 3.0	74,000	0.42
7 m (m’ma turbine)	8, 4.5	265,000	0.49

Izi ndi zomangira za zitsulo zopangidwa moyenera, pambuyo pa kuwonongeka kwa real-world. Monga chitsanzo, chida chopangidwa ndi 39 cm chamagetsi chonyamula chimawerengedwa kuti ndi 0.32, pomwe mtundu wathu umapatsa pafupifupi 0.39 kwa kukula kwake (Kishore, Coudron and Priya, 2013): choncho tikukhulupirira kuti chida choyamba chimafika pa 65 mpaka 90% ya mtengo wa dizilo, ndipo chilibe kwambiri kwa masentimita ozungulira, komwe kumagawidwa kwa laminar.

Njira ya upepo. Module yosasinthasintha imagwiritsa ntchito gawo la upepo wotulukamo. Kuwala kumagwa mozungulira ndi kubowola kwa kutalika kwa ma rotors otsegulidwa komanso mofulumira kwambiri kwa ma ducts (Tamaro et al., 2024; Richmond-Navarro et al., 2022). Ndi mpweya wokwanira, module yokumana nayo imasunga za 47% ya mphamvu nthawi zonse-aligned rotor angapeze. Version 1 anaganiza 100%.

Kusintha kwa mawonekedwe: korona pa khoma lakum’mawa

Tengani zonsezi pamwambapa ndipo kapangidwe kake kamakhala kokwanira: ma rotors akuluakulu komwe kuchuluka kwa Reynolds ndi kothandiza, m’maducts omwe amateteza komanso kufulumizitsa, okhazikika mwaulere komwe mpweya ukhoza kupita, motsutsana ndi mpweya wolimba kwambiri pamalo a nyumba yomwe imayenda bwino. Mzindawu ndi waukulu kwambiri ku Ulaya. Mphamvu ya mpweya yomwe imakhudza facade imakhala yotsika ndipo imasintha kudzera pamphepete; pamwamba pamphepete mwa mphepo, mphepo ndi 1.06 mpaka 1.25 nthawi yamphamvu pamphepete mwa mphepo, koma 0.38 nthawi pamene mphepo ikuyenda pansi (Mertens, 2006).

Mtundu uliwonse ndi 725 mm square: rotor ya 0.5 m yokhala ndi mabowo asanu mu chipinda chosapanga dzimbiri, ma vanes asanu a stator omwe amabwezeretsa mpweya wozungulira ndikuyendetsa jenereta wa 50 mpaka 300 W, chingwe chopanda madzi komanso board imodzi yotseka ndi kutsatira kwamphamvu kopitilira muyeso. Two rows make a 1.45 m tall crown on steel rails above the parapet. Mmodzi munthu angachotse module kunja ndi kusinthanitsa izo.

Masambawa si oyenera kudyetsedwa. Model amapanga iwo kwa Reynolds mndandanda iwo adzaona, za 45.000 pa 6 m / s: choir 62 mm pafupi ndi root taper kuti 36 mm pa tip, twist kuchokera 38 ° mpaka 10 °, a design tip-speed ratio ya 2.5. Pa 6 m / s rotor amadula pa pafupifupi 700 rpm; zigawo zake zimayenda pa pafupifupi 30 m / s mu 10 m / s upepo, pang’ono kuposa theka la 79 m / s za ma turbine amphamvu.

The okhulupirika ziwerengero

M’malo mwake, m’mphepete mwa nyanja ya Atlantic, kuzungulira dziko lapansi kuli mapiri osiyanasiyana, mapiri apakati ndi mapiri apakati, ndipo pamodzi ndi mapiri onsewa, ali ndi malo ozungulira omwe amatchedwa mapiri a kumpoto. Makhalidwe apakati, ndi mndandanda wonse wa pessimistic-to-optimistic mu model data. Kugwiritsa ntchito mphamvu kumaphatikizapo kuwala kwa mphepo, turbulence (kuwonongeka kwa 5 mpaka 15%) ndi kupezeka (92 mpaka 97%). Mtengo wa mphamvu: 20 zaka pa 7% ya ndalama zosawerengeka, kukonza 2 mpaka 5% ya ndalama chaka chilichonse.

Kodi tambala akuti:

• Mtundu umapeza malo ake, kokha. Pa m² ya frontal, ma modules opangidwa ndi ducted (B) amadula omwewo omwe ali otsegulidwa (B0) pafupifupi 10 mpaka 30%, makamaka chifukwa chotolera bwino kuwala kwa dzuwa. Iwonso amapereka chitetezo, chida chosagwira ndi malo a stator.
• Thechiwiri rotor salipira. Amawonjezera za 6% mphamvu kwa 16% zambiri mtengo. A jet-engine-style multi-stage wind module ndi physics-otsika, si ambition-otsika.
• Ngati pali ma modules oyenda mozungulira nyanja, ndiye kuti amalipira. Mtundu wa korona wozungulira nyumbayo umalandira ndalama zokwana 55% pa modulu poyerekezera ndi mbali yoyenda mozungulira nyanja yokha, chifukwa nthawi zambiri zigawo zina zimakumana ndi kuwala kwa nyanja. Pa nyumba yathu yogwirizana (40 × 20 m, 45 m yaitali) korona yoyenera ndi yokhayokha: 60 m², pafupifupi $ 64,000, pafupifupi 9,500 kWh chaka chilichonse pamalo otentha, 2,600 m’chigawo. Malipiro amodzi a dzuwa pakhoma amagula pafupifupi 155 m² a mapaneli omwe amapanga pafupifupi 35,000 kWh chaka chilichonse.
• M’mizinda siyingathe kupikisana. Ulemerero wa micro utali uli ndi mbiri yoipa: 26 turbines mu Warwick Wind Trials anali ndi 0.85% ya mphamvu (Encraft, 2009), ndipo ma turbine atatu pa London’s Strata tower adatseka pambuyo potsutsana ndi kelele ndi kupweteka.

Pofuna kuyerekezera, nyanja yamphamvu ya US idali ndi 14 mpaka 16% yokhala ndi mphamvu yamagetsi $6,680 to $9,630 pa kW yoyikidwa mu 2024 ndi 2025 (PNNL Kugawanitsa Wind ripoti). Mtengo wathu wa korona ndi pafupifupi $ 6,300 pa kW yowerengedwa, m’malo ofanana, zomwe ndi umboni wosonyeza kuti mtengo wowerengera si wopanda chiyembekezo.

Chiyani chimatsimikiziridwa, chotheka ndi chofufuza

Proven (buku lachikhalidwe kapena woyenera): mphamvu ya upepo ndi Betz malire; 16/25 chitseko kwa rotors awiri; kuti ma ducts kuwonjezera mphamvu pa rotor malo koma si zoposa za Betz pa frontal malo; kuti zinyalala zochepa pa Reynolds mndandanda pansi pa pafupifupi 70,000 kuipa ntchito; kuti m’mphepete mwake wachitali palibe kudzera-mtsinje; kuti nthambi zokongoletsera upwind mtsinje; kuti nyumba-mounted micro turbines mu mizinda anachita bwino.

Kuti angapeze, ndipo pamene sangathe

Itha kupambana:

• Windy maofesi akuluakulu ndi malo opumira, monga kuwonjezera kwa dzuwa: upepo pa khoma la khoma limafika usiku, m’nyengo yozizira komanso m’madzi, pamene mapaneli a dzuwa amapanga pang’ono.
• Zipinda zazing’ono kapena zobiriwira. Mtengo umagwiritsa ntchito malire, osati malo a denga, ndipo sapikisana ndi mapaneli, mbewu kapena ma terrazas.
• Off-grid mphamvu pamene kaboni ndi mtengo: ma sensors, kuwala, zida za telecom, malo anyengo pa miyala, masamba ndi zigawo zakum’mwera.
• Mavuto omwe alipo kale: magalimoto ndi magalimoto a sitima, zitseko zamadzi ndi ma parapets a bridge, komwe kukhazikitsidwa kwa chigawocho kumalipira.
• Visibility ndi kuphunzira. A korona kuti amasintha ndi kafukufuku wa anthu a solar panel si; mfundo za sukulu, makumbuyo ndi zomangamanga landmark zimene.
