2. Axial fan design - Wikipedia

   en.wikipedia.org/wiki/Axial_fan_design

   The stall zone for the single axial fan and axial fans operated in parallel are shown in the figure. [4] The Figure shows the Stall Prone Areas differently for One fan and Two fans in parallel. [4] The following can be inferred from the graph : For the Fans operated in parallel, the performance is less when compared to the individual fans.

   Axial fans with five-inch (125 mm) impellers are also used in larger bathrooms, though they are much less common. Domestic axial extractor fans are unsuitable for duct runs over 3 m or 4 m, depending on the number of bends in the run, as the increased air pressure in longer pipework inhibits the fan's performance.

4. Centrifugal fan - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_fan

   A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).

5. Computer fan - Wikipedia

   Where noise is an issue, larger, slower-turning fans are quieter than smaller, faster fans that can move the same airflow. Fan noise has been found to be roughly proportional to the fifth power of fan speed; halving the speed reduces the noise by about 15 dB. [22] Axial fans may rotate at speeds of up to around 38,000 rpm for smaller sizes. [23]

   Fan blades and outlet guide vanes of GEnx-2B Detail of GEnx core The GEnx is derived from the GE90 with a fan diameter of 111.1 in (282 cm) for the 787 and 104.7 in (266 cm) for the 747-8. To reduce weight, it features 18 composite fan blades, a composite fan case and titanium aluminide stage 6 and 7 low-pressure turbine blades.

   AMCA Publication 201 - Fans and Systems. Part 2 of the Fan Application Manual, discusses the effect of inlet and outlet connections on fan performance. It includes separate axial fan factors and is aimed primarily at the designer of the air moving system. AMCA Publication 202 - Troubleshooting. Part 3 of the Fan Application Manual, helps to ...
