Numerical Study of Coupled Fluid Flow and Heat Transfer in a Rectangular Domain at Moderate Reynolds Numbers using the Control Volume Method
Authors
Abstract:
In this paper, we have used a control volume method to investigate the problem of a fully coupled fluid flow with heat transfer in a rectangular domain with slip wall boundary conditions. We have used this method to solve the governing equations and thereby to compute the convective and diffusive fluxes at the cell faces of the control volumes considered around the grid points of computational domain.
