The article reports a numerical study of entropy generation in double-diffusive convection through a square porous cavity
saturated with a binary perfect gas mixture and submitted to horizontal thermal and concentration gradients. The analysis
is performed using Darcy–Brinkman formulation with the Boussinesq approximation. The set of coupled equations of mass, momentum,
energy and species conservation are solved using the control volume finite-element method. Effects of the Darcy number, the
porosity and the thermal porous Rayleigh number on entropy generation are studied. It was found that entropy generation considerably
depends on the Darcy number. Porosity induces the increase of entropy generation, especially at higher values of thermal porous
Rayleigh number. 相似文献
