The phase-averaged flow characteristics around a forward-swept axial fan model were investigated using a two-frame PTV method. The velocity fields in the sagittal and axial planes show clearly the periodic variations of flow structure and periodic shedding of the tip and trailing vortices according to the fan blade phase.
