Axial Fan Blade Design

Blade design wingtip with certain versions also featuring innovative peripheral components such as guide vanes diffuser and flowgrid.

Axial fan blade design.

In this video we ll be demonstrating the aerodynamic design of an axial low pressure fan including a cfd simulation. Axial flow fan design. 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 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 number and shape of the blades.

First you create a new project choosing the ventilator design module. Axial flow fans 1 0 definition of axial fans an axial flow fan moves air or gas parallel. Blade element theory 7. Axial fans with three kinds of blades are discussed and compared under design and off design conditions.

Testing of axial flow fans. The flow is axial at entry and exit. Insert the design point of the fan. Fan laws set of laws that predict perfor mance changes if one or more parameters are changed from one fan or operating condition to another.

Free vortex velocity distribution 6. The structural design of the fan blade was performed by one of the project partners and does not form part of this paper. The axiblade product range gets more out of the standard market footprint than any other axial fan. This creates the quieter axial fans required for the broad selection of industrial applications multi wing america services.

S series sickle shaped metal blades sheet steel or die cast aluminum. Under design conditions the total pressure efficiency of the axial flow fan with the forward swept blade is the highest and the c type blade has slightly lower efficiency while the straight blade has the. Ideal flow 1 3 frames of references 1 4 co ordinate system and components of velocity 1 5 velocity triangles on be turbine. Axial flow fan design procedures depend largely on the work.
