Heat transfer enhancement techniques are used in heat exchanger systems in order to enhance heat transfer and improve the thermal performance. Several methods are applied in order to improve thermal performance of heat transfer device such as treated surface, rough surface and incorporation of inserts. My work focuses on use of various Ribs to enhance heat transfer. The ribbed wall destabilized the flow. The separations and reattachments over the ribbed wall increase fluid mixing, create flow unsteadiness, interrupt the development of the thermal boundary layer and enhance the heat transfer. In this paper CFD analysis of different shape ribs such as V-ribs, (simple and broken v-ribs), triangular and rectangular ribs placed in rectangular duct has been performed. The work carried out in two stages: 1. Modeling of ribs for different shapes. It has been done in CATIA. 2. Analysis of flow and predict the best suited Rib among the various ribs considered. Analysis has been done in ANSYS CFD.
