![]() This indicates that consideration of local thermal non-equilibrium is of highly important. It is shown that internal heat exchanges inside the porous medium, represented by Biot number, dominate the temperature fields and Nusselt number. The conducted analyses further include evaluation of the rate of entropy generation within the porous medium. This results in the calculation of the temperature and concentration fields as well as the local and surface-averaged Nusselt and Sherwood numbers. Through employing appropriate change of variables, the governing equations in cylindrical coordinate are reduced to nonlinear ordinary differential equations and solved using a finite difference scheme. The non-equilibrium thermodynamics including Soret and Dufour effects and local thermal non-equilibrium are considered. This paper investigates forced convection of heat and mass from the catalytic surface of a cylinder featuring non-uniform transpiration and impinging flows in porous media.
