axial-flow fan

axial-flow fan

axial-flow fan
1. One of the following types of fans: vaneaxial, tubeaxial, or propeller. Such fans impart energy to the air by giving it a twisting motion. They are specified by blade shape, ratio of hub-to-tip diameter, pitch of the blades, and number of blades. Guide vanes may be added to straighten the flow and increase the efficiency.

The design problem for the axial-flow fan considered in this article involves the determination of the optimal shape of fan blades for the axial-flow fan based on the desired pressure head and volumetric flow rate of the fan.
radius = 0.654 percent chord The design problem for axial-flow fan blade considered involves the determination of the optimal shape of fan blade for the axial-flow fan based on the desired airflow rate.
To optimize the 3D shape of an axial-flow fan blade based on the desired airflow rate, the geometry of the redesigned fan blade has to be generated by using four primary design variables: the blade root attack angle, blade numbers, the blade root chord ([L.sub.r]), and blade end chord ([L.sub.e]) which enables the shape of the fan blade to be calculated by CFD, then the best parameters among the array of parameters in the candidate table for the required design problem can be selected and optimized.
