Use of rib turbulators is an effective technique to enhance the rate of heat transfer to gas flow in the gasturbine blade which enhances its cooling by creating turbulence over the boundary of the wall. The heat transfer in turbulent boundary layer will be more when compared to the laminar boundary layer.In this research ,sharp boots hap edribsofsizes 3mm, 6mm & 9mm each in rectangular channels, have analyzed computationally and compared with parameters like that with the rectangular channel without ribs using ANSYS 15.The above models have been analysed using Reynolds number of 10000, 15000, 20000 and 30000. It is predicted that different size of ribs will enhance the heat transfer rate and pressure drop in the rectangular channel section. In this research, the Temperature, Wall Heat Transfer Coefficient, Average Heat Transfer Coefficient, Friction factor, Velocity, Eddy viscosity, Pressure and Pressure drop of developed turbulent flow in rectangular channel of cross section 100*80*300mm will be compared.
