Axial Flow Fan Blade Design

Taking an axial fan as the research object the whole 3d numerical simulation was conducted by using ansys cfx.

Axial flow fan blade design.

A shaft drives a central drum which is retained by bearings inside of a stationary tubular casing. Guides or stator vanes serve to smoothen straighten the airflow and improve efficiency. Pᵢ is the pressure of the air at the inlet edge of the fan blades. Search google scholar for this author.

Three design options straight blades c type blades and forward swept blades are examined in this paper. An optimal design of axial flow fan blades by the machining method and an artificial neural network show all authors. Fan static pressure is actually fan total to static pressure it is.

Consider the use of the term fan static pressure there are two terms used for fans namely fan total pressure and fan static pressure. First you create a new project choosing the ventilator design module. National huwei institute of technology department of automation engineering yunlin taiwan see all articles by this author. Page 7 of 35 the basics of axial flow fans fan ring diameter inside diameter of fan housing at the plane of fan.

Stalling occurs only if there is insufficient air entering into the fan blades causing separation of flow on the blade surface. W is the width of the blades in a centrifugal fan parallel to the axis of rotation of the impeller. Surging or the unstable flow causing complete breakdown in fans is mainly contributed by the three factors. ρᵢ is the density of the air at the inlet edge of the fan blades.
