   The Emerson "Heat Fan", the first ceiling fan to use a stack motor A close-up of the dropped flywheel on a FASCO "Charleston" ceiling fan Stack-motor ceiling fans. In the late 1970s, due to rising energy costs prompted by the energy crisis , Emerson adapted their "K63" motor, commonly used in household appliances and industrial machinery, to be ...

   en.wikipedia.org/wiki/High-volume_low-speed_fan

   A High-volume low-speed fan. A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. [1] HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed."

   Other experiments made in 2004 with a wall jet along a circular wall show that Coandă effect does not occur in a laminar flow, and the critical ⁠ h / r ⁠ ratios for small Reynolds numbers are much smaller than those for turbulent flow. [16] down to ⁠ h / r ⁠ = 0.14 with a Reynolds number of 500, and ⁠ h / r ⁠ = 0.05 for a Reynolds ...

   At Mapang, there were gates, guards and razor wire. Darting birds and bougainvillea. Tin roofs, slatted glass windows, listless ceiling fans running off solar power. The main room was hung with a portrait of the staff, as well as an admonition to ALERT US if anyone not in the picture was seen walking the grounds.

6. Talk:Ceiling fan - Wikipedia

   FYI, "Snugger" is a trademark; it's Emerson's name for their hugger-style fan. Personally, I disagree that a separate section needs to be added. Hugger fans are no different from any other ceiling fan in any way, except for the fact that they don't have a downrod--something which is entirely unrelated to the fan's operation.

7. Axial fan design - Wikipedia

   en.wikipedia.org/wiki/Axial_fan_design

   An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...
