Abstract

Abstract : Purpose: – The purpose of this paper is to examine the effects of thick wall parameters of a cavity on combined convection in a channel. In other words, conjugate heat transfer is solved. Design/methodology/approach: – Galerkin weighted residual finite element method is used to solve the governing equations of mixed convection. Findings: – The streamlines, isotherms, local and average Nusselt numbers are obtained and presented for different parameters. It is found heat transfer is an increasing function of dimensionless thermal conductivity ratio. Originality/value: – The literature does not have mixed convection and conjugate heat transfer problem in a channel with thick walled cavity.
