Axial flow fan blade design.

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. Fan static pressure is actually fan total to static pressure it is. Guides or stator vanes serve to smoothen straighten the airflow and improve efficiency.

Search google scholar for this author. An optimal design of axial flow fan blades by the machining method and an artificial neural network show all authors. Three design options straight blades c type blades and forward swept blades are examined in this paper. Consider the use of the term fan static pressure there are two terms used for fans namely fan total pressure and fan static pressure.

Taking an axial fan as the research object the whole 3d numerical simulation was conducted by using ansys cfx. In this video we ll be demonstrating the aerodynamic design of an axial low pressure fan including a cfd simulation. Axial compressors consist of rotating and stationary components. National huwei institute of technology department of automation engineering yunlin taiwan see all articles by this author.

W is the width of the blades in a centrifugal fan parallel to the axis of rotation of the impeller. Stalling occurs only if there is insufficient air entering into the fan blades causing separation of flow on the blade surface. First you create a new project choosing the ventilator design module. ρᵢ is the density of the air at the inlet edge of the fan blades.
