In this era demand of energy is rapidly increases. In the last decade researchers are focus on Heat Transfer rate. The heat transfer rate is future key solve the problem of energy demand and cost of energy. For the analysis of proposed system use Ansys CFD tool, it’s one of the best tool the analysis of liquid and floods use in both places industry as well as research labs. In the proposed work design 3D model of rectangular rib and M shape rib in Ansys and analysis the fluid flow behaviour in a duct of a solar air heater (SAH) with one of rib having rough nature and another rib having smooth nature. In this whole phenomena Reynolds number is an important parameter, there numbers are vary from 3800 to 1500.Also validate the whole model numerical model and compare result, Proposed M shape rib shows better performance as compare to other previous methods.
