室内空气自然对流的二维数值模拟

A Numerical Simulation of Natural Convection in a Building Interior Space

用具有SIMPLE算法,QUICK差分格式对封闭空腔内的流体自然对流进行了数值模拟计算,考察了Ra数对对流换热的影响.结果表明,在相同的条件下,随着Ra数的增加,对流换热加强.

Through SIMPLE, the natural convection flow and heat transfer in a building interior space are simulated for various Rayleigh number. The results are refered that the more is Rayleigh number, the stronger are convection flow and heat transfer in the same cases.
