Flow field around an entire stage of an axial cooling fan is analyzed using the three-dimensional unsteady Reynolds-averaged Navier-Stokes (RANS) equations with Shear Stress Transport (SST) turbulence model, aiming at the investigation of the cooling performance of the fan. The main focus in this study is on the effect of the distance between the cooling fan and the surface to be cooled. Detailed flow measurement is also executed using a slant hot-wire probe to clarify time-resolved flow structure as well as turbulent flow characteristics contained in the downstream flow of the fan. The numerical results are compared with the experimental data as well as the flow field in the vicinity of the fan blades. This study reveals the important role of the fan-surface distance in terms of flow rate and cooling performance.
