Abstract

The present study numerically investigates the forced convection from the pin–fin type of the heat sink with an inline and a staggered arrangement of fins for varying Reynolds numbers. It further investigates the effect of attaching wings along the length of the fins on flow and heat transfer characteristics. It has been observed that the Nusselt numbers increase and friction factor decreases with increase in Reynolds numbers irrespective of the shape of the fins as well as the way the fins are arranged. The staggered arrangement of pin fins provided better thermo-hydraulic performance than the inline arrangement and the performance is further improved when the wings are embedded on the downstream side of the fins.
