【摘要】 本文提出了一种使用积分方法求解两维、定常、不可压缩Navier-Stokes方程的有限元格式。它克服了方程中对流项给数值方法带来的困难,使涡量的对流扩散方程和流函数方程一样具有同样形式的泛函。数值实验表明:使用这种方法计算是收敛的。它不仅可以节省计算时间而且还可以节省大量的存贮单元。更多还原

【Abstract】 In this paper, the finite element scheme using the integral method has been proposed to solve two-dimensional steady-state imcompressible Navier-Stokes equations ana remedy the computational difficulty arising from the convective term in the equations, which makes the stream function equation and the vorticity equation have the same functional. Calculating by this finite element scheme takes less computational time and saves a lot of memories and is convergent.更多还原
