三维层流自然对流换热边界层方程的数值解法

采用坐标变换及凯勒单元法求解强制对流换热边界层方程已比较成熟，但对自然对流换热的求解还未见报道。为了检验此方法用于求解自然对流换热的计算精度，采用该方法数值求解了竖窄条三维层流自然对流换热边界层方程，计算结果与前人的实验结果相符。结果表明，用此方法求解三维层流自然对流换热边界层方程是可行的。

Numerical Computation of 3-D Laminar Boundary Layer Equations of Natural Convection Heat Transfer

Coordinate transformation and Box method already succeed in solving boundary layer equations of compelling convection heat transfer,but the solution of natural convection heat transfer has not been informed.For examining the compute accuracy of solving natural convection heat transfer by using this method,this paper numerically computes 3 D laminar boundary layer equations of natural convection heat transfer of stand strip by using this method,the computational results agree with the experimental data from the published paper.The results shows that using this method to solve the equations is feasible.
