Double Diffusion Due to Centrally Heated Strip in Porous Material

  • 502 Accesses

Part of the Springer Proceedings in Materials book series (SPM,volume 8)

Abstract

This work describes the analysis being carried out to find out the diffusion of heat and mass because of multiple sources of heat placed in the medium. A small heating strip is placed centrally apart from regular heating at the left surface. The height of the strip is varied to understand its effect on double diffusion in the medium. The mass diffusion occurs between the vertical surfaces of the cavity under the influence of concentration gradient as well as the thermal gradient. Finite element method (FEM) has been employed for solving the equations. Solution is obtained through an in-house code that works on FEM. The elements of the domain are selected such that they have triangular shape with three nodes. Solution of the equations is obtained following an iterative process, and the results are described using contour plots of concentration, isotherms, and streamlines.
