摘要：

Three dimensional thermocapillary convection in a cubical cavity is considered. The governing equations are cast in primitive variable form. The resulting Neuman problem for pressure needs an integral constraint to be satisfied before a converged solution can be obtained. A consistent finite differencing procedure which enables this integral constraint to be satisfied to machine accuracy is outlined. Solutions are presented for Marangoni numbers 1, 100 and 300 and compared with the corresponding two-dimensional solutions. © 1990.
