Abstract
In the current work, computational fluid dynamics investigation has been performed in case of air foil shaped pillars in heat sink with impingement of jet. The investigation has been made in terms of thermal and fluid attributes. Height diameter ratio is taken as design variable. The influence of design parameters has been focused on the response parameters like temperature, pressure, transfer of heat, convection coefficient, Nusselt number. The numerical model has been constructed to discuss the response parameters. The model has been validated with the available experimental and simulation results. With pillars, augmentation in height diameter proportion, almost 44% reduction in the temperature of the base has been noticed. Also 24% augmentation has been deduced in the convection coefficient, with an increase in the design parameter. Advancement in height diameter proportion leaded to 16% improvement in the Nusselt number.
