Axial Flow Fan Blade Design

First you create a new project choosing the ventilator design module.

Axial flow fan blade design.

Surging or the unstable flow causing complete breakdown in fans is mainly contributed by the three factors. Search google scholar for this author. Guides or stator vanes serve to smoothen straighten the airflow and improve efficiency. Axial compressors consist of rotating and stationary components.

In this video we ll be demonstrating the aerodynamic design of an axial low pressure fan including a cfd simulation. Consider the use of the term fan static pressure there are two terms used for fans namely fan total pressure and fan static pressure. Three design options straight blades c type blades and forward swept blades are examined in this paper. Taking an axial fan as the research object the whole 3d numerical simulation was conducted by using ansys cfx.

Fan static pressure is actually fan total to static pressure it is. 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.

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. A shaft drives a central drum which is retained by bearings inside of a stationary tubular casing. W is the width of the blades in a centrifugal fan parallel to the axis of rotation of the impeller.
