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.
