摘要：

This experimental study, applied to axial fans with three different types of sweep (backward, radial and forward), aims at quantifying the 3D structure of the flow field from unsteady velocity measurements. The hot-wire anemometry is used to measure the velocity components in the nearfield, downstream of the fans. The data analysis leading to averaged and turbulent velocities, the components of the Reynolds' stress tensor and the turbulent kinetic energy is presented in order to illustrate the influence of the sweep. A spectral analysis is also performed. (c) 2006 Elsevier Ltd. All rights reserved.
