The present work numerically investigated the impact of Rhombus prism obstacle on heat transfer and fluid flow characteristics in a parallel plate channel having laminar flow regime with constant thermo-physical properties. Reynolds Numbers 50, 100, and 150 and fixed blockage ratio (b) of 0.5, were used to performed computations. Two dimensional Navier Stokes and energy equations were numerically solved for fluid flow and temperature field simulation, using control volume method on FLUENT 6.3 while the required unstructured triangular mesh was generated using GAMBIT. It is clearly illustrated from results that heat transfer performance significantly improves with presence of Rhombus prism obstacle. In compared to plane channel, Rhombus prism having 0.5 blockage ratio increases the 2.78%, 7.90% and 11.73% more Nusselt Number at Reynolds Number of 50, 100, and 150 respectively.
