摘要

This study presents a transient two-dimensional computational model of a combined natural convection, conduction, and radiation in a cavity wit an aspect ratio of one containing air as a non participant fluid. The cavity has two opaque adiabatic horizontal walls. one opaque isothermal vertical wall. The oposite vertical wall is a semitransparent wall that consits of a 6 mm glass sheet with a solar control coating of SnS-Cu_xS facing the inside of the cavity, ermitting solar radiation exchanges between the cavity and its surroundings. The momentum and energy equations in transient state were solved by finite differnces suing the ADI technique. Coupled to this equations are the transient conduction equation and the radiative energy flux boundary conditions, The results in theis paper are limited to the range of 10~4<=Gr<=10~6 with an isothermal vertical cold wall of 21degC, outside air temperatures (T_0) of 35degC and incident solar radiation of AM2 (750 W/m~2 mormal to the semitransparent wall. A Nusselt number correlation as a function of the Rayleigh number is presented.
