The present paper represents experimental investigation of heat transfer from plain heat sink and modelling, simulation in CFD to investigate the fluid flow and heat transfer characteristics of a fin arrays with lateral circular perforation under mixed convection mode. The simulation is carried out using the fluid flow ICEM- CFD of ANSYS V14.0. In this study, results shows that formation of the stagnant layer around the solid fin array which slow-downs the heat dissipation rate. The increase in the fluid flow movement around the fin results increase in the heat dissipation rate. It can be achieved by creating perforation to the fins. The analysis is carried out with CFD model to investigate flow pattern, temperature variations in computational domain, heat transfer coefficients & Nusselt no .Analysis is carried with both plane and perforated fin arrays with different size of CFD domains in order to ensure results with different fin spacing. A constant heat flux is assumed for heat sink
