Abstract: The use of ribs is one of the vital methods of improvement of the performance of thermal systems, for example, the cooling channel of the heat exchanger, solar air heater, etc. There are many benefits of performing CFD simulation before experimentation to select rib parameters that will give the highest magnitude of the rate of heat transfer with the least magnitude of friction penalty. Therefore, considering the large scope of research for a thermal and fluid flow simulation of ribbed surfaces this review article is presented. Numerical studies performed by the researchers on rib geometrical parameters, and different rib arrangements affecting thermal performance have been reviewed and explored. The details of flow governing equations, turbulence model, discretisation scheme, grid size; the type used for CFD simulation have been discussed. This review article will certainly provide a vision to the researchers for fluid flow modification and thermal performance intensification using ribs in thermal systems.
