In this chapter, we discuss the combined influence of radiation and dissipation on the convective heat and mass transfer flow of a viscous fluild through a porous medium in a rectangular cavity using Darcy model. The governing non- linear coupled equations for the momentum, energy and diffusion are derived in terms of the non-dimensional stream function, temperature and concentration. The Galerkin finite element analysis with linear traingular elements is used to obtain the Global stiffness matrices for the values of stream function, temperature and concentration. These coupled matrices are solved using iterative procedure and expressions for stream function, temperature and concentration are obtained as a linear combinations of the shape functions. The behaviour of temperature, concentration, Nusselt number and sherwood number are discussed computationally for different values of the governing parameters.

Abstract


In this chapter, we discuss the combined influence of radiation and dissipation on the convective heat and mass transfer flow of a viscous fluild through a porous medium in a rectangular cavity using Darcy model. The governing non- linear coupled equations for the momentum, energy and diffusion are derived in terms of the non-dimensional stream function, temperature and concentration. The Galerkin finite element analysis with linear traingular elements is used to obtain the Global stiffness matrices for the values of stream function, temperature and concentration. These coupled matrices are solved using iterative procedure and expressions for stream function, temperature and concentration are obtained as a linear combinations of the shape functions. The behaviour of temperature, concentration, Nusselt number and sherwood number are discussed computationally for different values of the governing parameters.
