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 ...
A cross-flow fan is a centrifugal fan in which the air flows straight through the fan instead of at a right angle. The rotor of a cross-flow fan is covered to create a pressure differential. A cross-flow fan has two walls outside the impeller and a thick vortex wall inside. The radial gap decreases in the direction of the impeller rotation.
Axial fans; Blowers; Axial-flow pumps; Centrifugal Pumps; Turbopumps; While creating a new design, AxSTREAM allows the user to start from initial inlet and outlet parameters, geometrical constraints, required mass flow rate (capacity) and rotational speed to perform preliminary design, 1D/2D calculation and optimization.
The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...

Vaneaxial fans – These axial flow fans have a higher pressure capability due to the presence of static vanes. Variable pitch axial fans – The blades on these axial fans are manually adjustable to permit the blade angle to be changed. This allows operation over a much wider range of volume/pressure relationships.
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).
Blade solidity is an important design parameter for the axial flow impeller and is defined as the ratio of blade chord length to spacing. Airfoil nomenclature. Blade Solidity = c/s; Where = / is the spacing; is the mean radius; is blade number
