Lattice Boltzmann Simulation of Heat and Mass Transfer in Solar-wall System

Abstract

Keyword: LBM; solar wall; heat and mass transfer; porous medium. Abstract: In this paper, the problem of heat and m ass transfer in Solar-wall System is solve d by lattice Boltzmann method. The lattice Boltzm ann equation is governed by the heat conduction equation. The heat transfer and flow characteristics for the Solar-wall System with air as heat transfer medium are sim ulated. It is found that the perfor mance parameters of the porous solar wall are influenced by the outlet air velocity and structure of the porous solar wall such as the porosity and the porous solar wall width.
