TLDR
In this paper, the authors investigated the effect of size of solid wall and its location inside the porous cavity on double diffusive convention and the heat and mass transfer behavior are governed by momentum, energy and concentration equations which are converted into a set of finite element equation with the help of Galerkin method.Abstract:
The present article deals with the issue of heat and mass transfer in a square porous cavity having a small solid wall or block inserted at various places at bottom surface. The main objective is to investigate the effect of size of solid wall and its location inside the porous cavity on double diffusive convention. The heat and mass transfer behavior are governed by momentum, energy and concentration equations which are converted into a set of finite element equation with the help of Galerkin method. The left surface of cavity is maintained at higher temperature and concentration, T h and C h as compared to that of right surface at T c and C c . The results are presented in terms of thermal, concentration and fluid flow profiles across the porous cavity.read more

Heat transfer in a porous cavity in presence of square solid block
TL;DR: In this paper, the effect of size of the square solid block and other physical parameters on the heat transfer rate from the hot surface into the porous medium was investigated. But the authors did not consider the effects of the number of square solid blocks in the cavity.
