摘要
采用ＴａｙｌｏｒＧａｌｅｒｋｉｎ（ＴＧ）有限元法离散轴对称流动问题的ＮＳ方程，以压力校正法求解不可压流场的各原始变量，并具体推导了相应的压力修正和速度修正方程的有限元列式，编制了计算程序，最后以同轴环形空间内的不可压粘性流动为例，验证了有限元列式及程序的正确性。
The governing equations of incompressible axisymmetric flow are solved by the Taylor Galerkin(TG) finite element methods,and the pressure correction method is adopted to obtain the primitive variables of the flow. Correspondingly, the FEM formula of pressure and velocity correction are derived. The numerical experiment of a flow between two rotating concentric cylinders shows that the formula and program are both correct.
