Abstract
Aim of present paper is to study the heat and mass transfer in porous cavity with respect to high concentration at lower half of left vertical surface. This is an extension of work where high concentration is supplied at upper half of cavity. The right vertical surface is maintained at constant concentration Cc such that Cw>Cc. The left and right vertical surfaces of cavity are maintained at isothermal temperature Tw and Tc where Tw>Tc. Darcy model is used to describe the flow in porous medium. The governing partial differential equations are non-dimensionalised to reduce the number of variables involved. Finite element method is used to convert the governing equations into a set of algebraic equations and then solved for the square porous domain meshed with triangular elements.
Keywords:
Double diffusion, finite element method, lower half concentration, porous media,
