The short version: a wall of computer fans on a facade cannot work, a crown of larger ducted rotors on a windy roof edge can make real electricity, and it won’t beat solar panels on price unless several things we can test turn out well. Every figure below comes from our open model (code, data).

Ụdị 1, nakwa ihe mere ọ ji arụ ọrụ

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. Ọ bụ foto mara mma. Ọ na-akwụsị n’ihi ihe atọ, n’ụzọ dị mkpa.

N’ime fatịlaịza dị ike, ikuku na-akwụsị (ndị injinia na-akpọ ya stagnation) ma na-agbagharị elu, ala na n’akụkụ. Ọ bụrụ na ọbụna fan niile nwere 30 cm gap n’azụ ya, mepere na akụkụ na elu, ịrụ ọrụ na-eweta oke: ikuku niile na-abanye na 1,800 m² nke ndị fan ga-enwe ike ịhapụ site na ihe dịka 39 m² nke agwa, ya mere ọ nwere ike ịgagharị ndị fan na enweghị karịa 2.2% nke ọsọ ikuku. Ike na-aga n’ihu na ịkwaịb nke ọsọ, yabụkwa ọwa ahụ ga-echekwa n’okpuru 0.01% nke ihe ndị ahụ ga-eme ka ndị fan dị n’ebe ahụ nọ n’enweghị nsogbu. Measurements behind real ventilated cladding agree: 0.2 to 0.6 m/s of cavity airflow in winds of up to 5 m/s (Salonvaara et al., 2007). Kpụgharịa 3D móòdù n’elu na ákàrà 1 ka ịhụ ya: ọ̀dọ̀ ikuku na-akwụsị na wọ́lọ̀ọ̀tụ̀ nakwa ịkwaga.

**2. Tiny blades na-arụ ọrụ nke ọma. ** A 120 mm fan blade nwere a chord nke banyere 2 cm. Ọnụ mmiri na-agbagharị n’ime ya na ọnụọgụ Reynolds dị nso na 10,000, usoro ebe wings na-ahapụ ọtụtụ nke ọnụọgụgụ ha: ụgbọ elu dị mma na-eme ka “ọtụtụ karịa iwu nke magnitude” n’elu ọnụọgụgụ Reynolds dị mkpa nke ihe dịka 70,000 (Lissaman, 1983). A na-enyocha ihe ndị dị n’ụdị sentimita-ọnụ ọgụgụ nke nwere ike ịbawanye ike ruo 9% (Howey, Bansal na Holmes, 2011); rotor fan 10 cm nke kọmputa a na-eji dịka turbine na-enye 28 mW na 5 m / s, banyere 4% nke ike ikuku site na ọnụọgụ anyị (Federspiel na Chen, 2003). Kọmputa fanị bụ nke e ji kpụga ikuku, ọ bụghị ka a dọọrọ ya.

**3. Ndị mmadụ na-ahapụ ihe ole na ole ha na-eme. ** A fan motor na-enye akụkụ nke watt na volts ole na ole nwere ike ịnwụ 10 ruo 40% n’ime diode rectifier naanị. Anyị na-atụ anya na ọnụọgụgụ nke ihe niile site n’ime fan ruo griiz bụ 54%.

Ọ bụrụ na a hapụ ihe kpatara mbụ n’ụzọ zuru ezu (ụlọ elu fan), ụdị 1 ga-efu ihe dị ka $4.20 per kWh on a windy coast and $18 n’obodo, afọ iri ruo otu puku ugboro ọnụ ahịa nke rooftop solar.

Ike a na-ebu site n’ụgbọelu site n’ebe A bụ P = ½ ρ A v³, na ike ikuku ρ = 1.225 kg/m³. Nke a bụ ihe niile: na 6 m/s square mita na-eburu 132 W, na 12 m/s 1,058 W. N’ime afọ, ụlọ elu obodo nwere 4 m/s nke ikuku na-enye ihe dịka 75 W kwa m²; osimiri dị n’akụkụ oke osimiri na 6.5 m/s banyere 321 W kwa m².

Gịnị ka rotor nke abụọ nwere ike ịgbakwunye. Rotors abụọ n’ime usoro (dịka ọnọdụ nke jet engine) nwere ike ịbịaru nso na ọtụtụ 16/25 = 64% nke ike site na mpaghara rotor, na ọtụtụ ndị dị iche iche naanị 2/3 (Newman, 1986). A na-eji ụgbọala jet kpụpụta ihe ndị dị iche iche n’ihi na ọ na-adọta ikuku site n’ime ebe a na-echekwa ya nke nwere nnukwu ọdịiche n’ihe mgbaru ọsọ site n’ịkụ mmanụ. Ọnụ mmiri n’efu na-enyeghị mgbatị dị ka nke a: ọbụla n’ime usoro ndị ọzọ na-eme ka ikuku dịkwuo ala, ma na-ewepụkwa ikuku dị ala n’ụdị ngwaọrụ ahụ. Measured gains nke counter-roting wind rotors na-aga site na 0 ruo 60%, ma ọ dịkwa mma-controlled nnyocha gara aga cluster na 2 ruo 10% (Adema na ndị ọzọ., 2026 nyocha).

Gịnị ka stator vanes nwere ike ịgbakwunye. A na-ahapụ rotor ahụ n’ụgbọ mmiri, nakwa ọbụna ikuku nke swirl ahụ. N’ihe banyere ọnụọgụ nke obere rotor, ọ dị oke njọ: ihe kachasị mma Glauert rotor na-eru 0.42 na ọnụọgụ nke 1, 0.51 na 2 na 0.57 na 5. Ntọala vanes n’azụ rotor nwere ike ịnaghachi akụkụ ya. Enweghị onye chọpụtara nke a na turbine ikuku; n’ime propeller ụgbọ elu, vanes ndị ahụ nyere 2 ruo 5% (Li et al., 2017).

Gịnị ka duct nwere ike ịgbakwunye. A duct na-enwekwa flaịt brim (nke “wind lens” nke Kyushu University) na-ewepụ nrụgide n’azụ rotor ma na-adọta ikuku ọzọ site na ya. In wind-tunnel tests a compact brimmed diffuser raised the power coefficient from 0.37 for the bare rotor to between 0.7 and 0.88, relative to the rotor area, but to only 0.48 to 0.54 relative to the whole brim (Ohya and Karasudani, 2010). Nke ahụ bụ ihe na-atọ ụtọ: kwa mita square nke * mpaghara frontal *, ducts anaghị adịgide adịgide n’ebe Betz dị, “n’ịrụ ọrụ ike na-abawanye ihe kpatara elu 3 agaghị adịkarị”, na ducted turbines nwere “ihe karịrị afọ 50”. N’ebe ahụ, ọ dịghị ihe ịga nke ọma na-azụ ahịa” (van Bussel, 2007). Ọrụ kachasị ọnụ ahịa, FloDesign / Ogin, wepụrụ turbines ya n’ime ọnwa iri na ise ma wepụ ya na 2017 (Gipe, 2017).

Ụhara dị mkpa n’ihi na ọnụọgụgụ Reynolds. Anyị rụpụtara rotor kacha mma nwere ike na ọkara ọ bụla na móòdù mmegharị nke elementị-blade (Glauert’s optimal na mgbagharị, ntuziaka na ụdaụgbọ ahụ, nakwa a lift-ka-drag ratio nke na-agbapụta na ọnụọgụgụ Reynolds, site na ihenhọrọ ala-Reynolds dịka Selig’s SG6043):

Ha bụ n’elu maka ihenhọrọ-echekwara blade, tupu a na-ahapụ ya.
