Abstract: Structure of laminar flow and heat transfer in a two-dimensional plane channel with a built-in bluff body is investigated from the numerical solutions of complete Navier-Stokes and energy equations. The physical problem is a plane channel of hot walls in which a bluff body is introduced in order to enhance the heat transfer from walls to the flow. Two bluff bodies are tested; triangular prism (TP) and square cylinder (SC). The effect of obstacle position on heat transfer enhancement and pressure drop is the principal aim of this study. Numerical results show that heat transfer reaches its maximum value when the obstacle is placed in the central region of the channel, the augmentation in heat transfer exceeds 23.07% and 32.30% for SC and TP respectively at Re = 200 when compared to the case of flow without obstacle.
