Investigation of cooling efficiency of rim driven fans compared with conventional fans
Unlike most conventional fans, rim driven fans are not driven by an axisymmetric shaft but instead by the rim itself, thereby removing the need for a shaft. This is thus more effective and economical for the purposes of cooling for various appliances. A thorough steady CFD analysis was performed for...

| description | Unlike most conventional fans, rim driven fans are not driven by an axisymmetric shaft but instead by the rim itself, thereby removing the need for a shaft. This is thus more effective and economical for the purposes of cooling for various appliances. A thorough steady CFD analysis was performed for this quantitative investigation, including a grid independence study for verification of both
mesh models of both the rim driven fan as well as the conventional fan. Using a standard k-ro turbulence model on FL VENT™, the numerical results will reflect the intricate aspects of convective heat transfer in both models along with their flow visualization. A cooling efficiency parameter was formulated to compare the effective heat flux removed from the heat source by the respective fans thereby directly reflecting the aspect of cost. |
