摘      要：The present work highlights the application of finite element method to conjugate heat and mass in porous annulus. transfer Finite element discretization of double diffusion in porous medium having fixed in annular geometry is presented. The simplest of the two dimensional elements i.e. triangular element is made use of to divide the geometry of problem under investigation into a set of smaller segments. Galerkin method is applied to convert the equations that govern double diffusion in porous medium into a set of algebraic equations. The application of FEM results into 3 equation for each element which is then assembled into a global matrix to get the solution. There are three equations which results into three set of simultaneous equations in the form of global matrix. The formulation is discussed with respect to the solution methodology to be followed.
