Axial Flow 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 blade design. Taking an axial fan as the research object the whole 3d numerical simulation was conducted by using ansys cfx. National huwei institute of technology department of automation engineering yunlin taiwan see all articles by this author. Axial compressors consist of rotating and stationary components.

A shaft drives a central drum which is retained by bearings inside of a stationary tubular casing. Pᵢ is the pressure of the air at the inlet edge of the fan blades. ρᵢ is the density of the air at the inlet edge of the fan blades.

Fan static pressure is actually fan total to static pressure it is. Page 7 of 35 the basics of axial flow fans fan ring diameter inside diameter of fan housing at the plane of fan. First you create a new project choosing the ventilator design module. Axial flow fans as the name indicate draws the air and blows forward which moves in the axis of the fan there would be no centrifugal effect on the airflow generated.

Consider the use of the term fan static pressure there are two terms used for fans namely fan total pressure and fan static pressure. W is the width of the blades in a centrifugal fan parallel to the axis of rotation of the impeller. Guides or stator vanes serve to smoothen straighten the airflow and improve efficiency. An optimal design of axial flow fan blades by the machining method and an artificial neural network show all authors.
