摘　　要：本文利用椭圆型微分方程的数值求解,在圆截面三通管道内生成了非正交贴体网格系统,然后通过在该网格系统下数值求解三维Navier-Stokes方程,得到了不同Reynolds数下三通管道内层流流动的数值解。最后对计算结果进行了分析讨论。A 3-D grid system of Tee-junction based on non-orthogonal body- fitted coordinates is generated by solving Elliptically Partial Differential Equations. And, by solving incompressible Navier-Stokes equations on this grid system, a numerical prediction of the laminar flows in the Tee-junction at different Reynolds numbers is made. Finally, the results of the calculation are analyzed and discussed.
