Numerical Investigation of Fluid Flow and Heat Transfer in a Rectangular Channel with Longitudinal Vortex Generators

Rectangular ducts are used to transfer hot or cold air from one location to other. In case of hot air carriers where more heat has to be dissipated to atmospheric air during its travel, turbulence plays a key role in achieving this. For increasing the turbulence of fluid, the plane surface of duct is provided with different geometrical entities which result in increased heat transfer as compared to plane surface. There is also a pressure drop in fluid because of these disturbances occurring in the fluid. In this work, a number of appropriate designs for these vortex generators are made and simulation has been performed. A balance has been made between heat transfer and pressure drop so that overall effectiveness of the system is improved.
