التحليل العددي الثلاثي الابعاد للحمل الحراري والعشوائيه في مقطر شمسي
الملخص الانجليزي
Numerical results of double-diffusive natural convection are presented in a three-dimensional solar distiller.
The flow is considered laminar and caused by the interaction of the thermal energy and the chemical species
diffusions. Equations of concentration, energy and momentum are formulated using vector potentialvorticity
formulations in its three-dimensional form, then solved by the finite volume method. The Rayleigh
number is fixed at Ra=105 and the effects of the buoyancy ratio are studied for opposed temperature and
concentration gradients, with a particular interest to the three-dimensional aspects and entropy generation
