COMBINED RADIATION-NATURAL CONVECTION IN THREE-DIMENSIONAL VERTICALS

Abstract

In this article we studied the effect of radiative transfer and the aspect ratio on the 3D natural convection. Prandtl and Rayleigh numbers are respectively fixed at 13.6 and 105. Equations of natural convection are expressed according the vorticity-stream function formulation. This equations and radiative transfer equation are respectively descritized by volume control method and the FTnFVM. Obtained simulation show that the principal flow structure is considerably modified when the radiation-conduction parameter was varied. However, the peripheral spiraling motion is qualitatively insensitive to these parameters.
