It is quite usual that the small axial flow fan used for PCs is installed in narrow space. In such a case the fan performance
and flow field are supposed to be different from those of design conditions. In addition, influences that obstacles upstream
and downstream of the fan give to the fan performance are not well understood. In this study, we measure the flow field and
performance of a PC cooling fan used under realistic conditions. Furthermore, we compare calculated results with the
experimental results.
