Abstract

In this research, the effect of the number of fins and contribution of walls with and without fin to the amount of Heat transfer inside a straight channel has been investigated numerically. It contains 1, 3 and 5 fins separately. The Carboxymethyl cellulose aqueous solution (CMC) was considered as a power– low non-Newtonian fluid. The local Nasselt numbers, Heat transfer coefficient and pressure drop have been studied at some Reynolds and Prandtl number. From this study, it has been concluded that the increasing the number of fins on the wall helps to increase total Heat transfer but increasing rate of Heat transfer has nonlinear trend with increasing the number of fins. The rate of Heat transfer has decreasing trend due to differences in flow pattern. Also, the contribution of Heat transfer on the walls with and without fins is not regular process and depends on the specific location of the fins. The optimum Heat transfer and pressure drop are dependent on the number and spacing of the fins. Therefore, it is necessary to balance the amount of Heat transfer increased due to the increase in the number and area of the fins surface and the increase in the pressure loss associated with it.
