Simulation of Fully Developed Flow and Heat Transfer in Wavy Channels Using OpenFOAM

Wavy channels are known to be one of the passive methods for heat transfer enhancement and are widely employed in different heat exchanging devices. Heat transfer augmentation in the wavy channel can be achieved by interruption of thermal boundary layer growth due to generation of vortices. The present study deals with the modification of open-source computational fluid dynamics solver OpenFOAM to simulate fully developed flow and heat transfer in wavy channels with constant wall temperature boundary condition. Validation of numerical method has been confirmed by simulating the flow and heat transfer in plane and wavy channel and are compared with the existing literature.
