“…The effects of the Reynolds number (Re) and the fin height and spacing on the fluid flow and the heat transfer were examined. Yang et al [2] simulated the forced convection in a parallel plate channel. Constant temperature was considered in both upper and lower walls, and a transverse object was located at the lower channel wall.…”

This paper presents a numerical study of the thermal performance of fins mounted on the bottom wall of a horizontal channel and cooled with either pure water or an Al2O3-water nanofluid. The bottom wall of the channel is heated at a constant temperature and cooled by mixed convection of laminar flow at a relatively low temperature. The results of the numerical simulation indicate that the heat transfer rate of fins is significantly affected by the Reynolds number (Re) and the thermal conductivity of the fins. The influence of the solid volume fraction on the increase of heat transfer is more noticeable at higher values of the Re.

“…The effect of a change in the obstacle height, width as well as the thermal conductivity was investigated and an empirical correlation was established. Through the use of a stream function vorticity transformation, Yang et al [3] studied the influence of the aspect ratios of fins, the Reynolds number and the thermal conductivity ratio. They found that the optimum aspect ratio of a fin, corresponding to the fin with a maximum heat transfer rate, increases with increasing the Reynolds number but decreases with the thermal conductivity ratio.…”

The main objective of this work is to examine the heat transfer changes induced by the presence of heat generating obstacles and that for non-Newtonian fluid flow within a parallel plate channel. The effects of the two obstacle height and the distance between them, on the flow structure and Nusselt number are examined. The Finite Volume Method is used to discretize the conservation equations of mass, momentum, and energy. The SIMPLER algorithm is applied to remove the checkerboard pressure problem. The results are discussed in terms of streamlines and the Nusselt number for three combinations of height and separation distance of the two obstacles. Two recirculation zones are observed for all the cases with different intensity varying with the size of the obstacle and the separation distance. Likewise the results show that the heat removal, occurring by the Nusselt number variations, is widely affected by the size of the obstacles as well as by the distance between them.
