Numerical and Experimental Analysis of Perforated type of Heat Sink
Authors: ,
Abstract: This paper numerically studied the heat transfer and flow characteristics of plate pin-fin heat sink, cross cut and perforation heat sinks using commercial CFD software FLUENT. The governing equations are discretized by using a control volume based finite-difference method. The coupling of the velocity and the pressure terms of momentum equations are solved by the SIMPLE algorithm. The well-known k–ε two-equation turbulence model is employed to describe the turbulent structure and behavior. The parameters include the inlet air flow velocity (Uin=6.0, 7.0, 8.0 and 9.0 m/s), perforation and cross cut lengths. At given number of perforations, decrease thermal resistance is observed at three numbers of perforation along with increases in pressure drop in comparison with experimentally studied
