Abstract — In our analysis, CFD was used and the model was developed on NX-8. In order to verify the present CFD model, the thermal resistance and the pressure drop are compared with the available experimental results present in the literature and the design of slotted fin heat sink (SFHS) having Pitch is 5, 10 and 15. In this study, the simulations of SFHS at various wind velocity i.e., 6.5, 9.5 & 12.0m/s and the configurations of Pitch fins design are proposed.

The results show that increasing wind velocity could reduce the thermal resistance and increase the pressure drop simultaneously. The thermal resistance of the SFHS is lower than that of the Flat Plate fin heat sink (FPFHS) at the same wind velocity and the pressure drop of the SFHS is much higher than that of the FPFHS.
