Thermal Fluid Analysis of Different Combinations of Jet Channel and Air Foil Pillars with CuO–Water Nano Fluid

Small-scale thermal devices are very effective and interesting to use for the applications which involve large amount of heat flux. The use of Nano particles in the base fluid like water also augments the various properties which help in the heat dissipation from the components subjected to high temperatures. In the current study, the various combinations of jet-channel and pillars have been investigated comparatively. CuO–water-based Nano fluid is used along with the air foil pillars in a heat sink to augment the heat transfer. Comparative analysis has been executed for the different parameters like temperature, heat exchange coefficient, Nusselt number and thermal resistance. The study has been carried out for a constant value of heat flux at the bottom surface. Minimum temperature is found in case of jet-pillar combination. The channel flow diminished the heat exchange coefficient.
