摘要: 在本文中,我们提出了一个稳定的求解扩散——对流方程的Саульев型格式,并提出了它的单调性和自调性。最后将其应用于二维粘性不可压缩圆柱绕流的计算,与已发表的数值结果和实验结果相比较表明我们的计算结果是好的。

Abstract: A New difference scheme, Saulev scheme, is proposed for solving diffusion-convection. equation. Its stability, monotone and Self-adjust are analysed too. Numerical Solutions have been obtained for incompressible viscous flow past a circular cylinder at Reynolds numbers up to 400 with this scheme. Comparing with experiment data and published results, our result is good.
