G602 Experimental and Numerical Studies on Aerodynamic Performance and Flow Field of a Cooling Fan Used in a Narrow Space(2)

Abstract

Cooling fan in PCs or small vacuum pumps is generally used in narrow space. In such cases the fan performance and flow field are quite different compared to these in design usage. In this study, we measure the flow field and performance of the fan used under realistic conditions. We use slant-type hot-wire probe for a measurement and performed a detailed measurement about a three dimensional unsteady flow field. Furthermore, we compare calculated results with the experiment result.
