How does a crossflow fan work?

Due to the two-dimensional nature of the flow, the fan readily integrates into a wing for use in both thrust production and boundary-layer control. A configuration that utilizes a crossflow fan is located at the wing leading edge is the fanwing. This design creates lift by deflecting the wake downward due to the rotational direction of the fan, causing large Magnus force, similar to a spinning leading-edge cylinder. Another configuration utilizing a crossflow fan for thrust and flow control is the propulsive wing. In this design, the crossflow fan is placed near the trailing edge of a thick wing and draws the air of the wing's suction (top) surface. By doing this, the propulsive wing is nearly stall-free, even at extremely high angles of attack, producing very high lift. The external links section provides links to these concepts.

How does a fan make noise?

Fans generate noise from the rapid flow of air around blades and obstacles causing vortexes, and from the motor. Fan noise is roughly proportional to the fifth power of fan speed; halving speed reduces noise by about 15 dB.

What is the name of the assembly of blades and hubs?

Drag dance numbers also utilise larger hand fans as a way to add flair and as a prop, used to emphasise movements in the dance.

How does a hand fan affect the body temperature?

On human skin, the airflow from handfans increases evaporation which has a cooling effect due to the latent heat of evaporation of water. It also increases heat convection by displacing the warmer air produced by body heat that surrounds the skin , which has an additional cooling effect, provided that the ambient air temperature is lower than the skin temperature – which is typically about 33 °C (91 °F). Fans are convenient to carry around, especially folding fans.

What was the purpose of screen fans?

The screen fan was mainly used inside the interior of the house. In 18th and 19th century paintings of interiors one sometimes sees one laying on a chimney mantle. They were mainly used to protect a woman's face against the glare and heat of the fire, to avoid getting "coup rose", or ruddy cheeks from the heat. But probably not in the least it served to keep the heat from spoiling the carefully applied make-up which in those days was often wax-based. Until the 20th century houses were heated by open fires in chimneys or by stoves, and the lack of insulation made many a house very draughty and cold during winter. Therefore, any social or family gathering would be in close proximity to the fireplace.

What are the pads on a water cooler?

The pads are where the air cooling occurs, as water delivered to the pads by the water pump evaporates under the air blown through the pads by the cooler motor. Pads for evaporative coolers come in many types, including foamed polyester, slit expanded paper, and wood strips. The most common and cheapest cooler pads are the ones made from wood strips. These pads work well, but if the strips get loose, they can clog up the pump, so placing an extra screen around the pump can be a good idea.
