Common household tower fans are also cross-flow fans. Much of the early work focused on developing the cross-flow fan for both high- and low-flow-rate conditions, and resulted in numerous patents. One interesting phenomenon particular to the cross-flow fan is that, as the blades rotate, the local air incidence angle changes. The result is that in certain positions the blades act as compressors pressure increase , while at other azimuthal locations the blades act as turbines pressure decrease.
Since the flow both enters and exits the impeller radially, the crossflow fan is well suited for aircraft applications. 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 off 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.
A cross flow fan, is a centrifugal fan in which the air flows through the fan, rather than through an inlet. The rotor of a cross flow fan is covered to create a pressure differential. When used in household fans, cross flow fans have smaller opening on one side and a larger opening on the other.
Cross flow fans have openings of different sizes on the front and rear sides. The resultant pressure difference allows air to flow straight through the fan, even though the fan blades counter the flow of air on one side of the rotation. Cross flow fans give airflow along the entire width of the fan, however, they are noiser than ordinary centrifugal fans presumedly because the fan blades fight the flow of air on one side of the rotation unlike normal squirrel cage fans. Cross flow fans are often used in air conditioners , automobile ventilation systems, and for cooling in medium-sized equipment such as photocopiers.
The action of a fan or blower causes pressures slightly above atmospheric, which are called plenums. Bladeless Indirect viscous-shear fan[ edit ] This section may be too technical for most readers to understand.
Please help improve it to make it understandable to non-experts , without removing the technical details. December Learn how and when to remove this template message This is an indirect blower system which collects pressurized airflow from a standard blower device that can be of any type mentioned in this article, and directs the collected airflow through a hollow tube or toroid, blowing a thin high-velocity laminar airflow from holes or a continuous slot across the surface of the tube or toroid.
These fans have a three-dimensional mixed-flow impeller in a lower compartment. Air is drawn in and compressed, before being expelled through an annulus, and accelerated over an airfoil lamp. Inducing and entraining ambient air through viscous shearing, the loop-shaped upper section multiplies the total airflow many times. The high velocity laminar airflow tends to drag ambient air along with it, due to viscous shear.
Uncommon types of fans[ edit ] Main article: Bellows Diagram of a single-acting hand bellows Bellows are also used to move air, although not generally considered fans. A hand-operated bellows is essentially a bag with a nozzle and handles, which can be filled with air by one movement, and the air expelled by another. Typically it would comprise two rigid flat surfaces hinged at one end, where a nozzle is fitted, and with handles at the other.
