This paper presents the design and experiment of a high performance three-stage axial fan with forward swept blades.

An experimental investigation of effects of two kinds of streamwise-grooved blades on the performance of an axial-flow fan was performed on an axial fan test rig.

In this paper,a numerical method is used to investigate the effects of a winglet attached to an axial fan on the performance.

Research on the performance improvement of the low pressure axial flow fan;

The internal flows of axial flow fans with skewed-swept in leading-edge;

The formation and development of the tip vortex in the axial flow fan with a shroud cover- ing only the rear region of the rotor tips had been analyzed numerically by solving three-dimensional Reynolds-averaged Navier-Stokes viscous partial differential equations with the Spalart-Allmaras tur- bulent model.
