Efficient performance of automotive centrifugal cooling fan depends on many geometrical parameters like number of blades, its thickness, inlet angle, outlet angle, and blade diameter ratio. To examine the effect of these parameters experimentally, it requires large number of prototypes to be made. It is a time consuming process. It this paper, we report the systematic procedure to design a simple experimental setup to measure the fan performance. A 3D CFD model was developed and validated with the results obtained from the experiments. The results suggest that irrespective of fan design, fan performance tends to become equal at high system resistance.
