摘要
该文构造了计算二维粘性不可压缩流动的 Ｆｏｕｒｉｅｒ－Ｃｈｅｂｙｓｈｅｖ拟谱格式，严格证明了其广义稳定性和收敛性，并给出了数值结果，该文的理论分析为此类混合逼近的误差估计提供了一个框架。
Fourier-Chebyshev pseudospeotral scheme with mixed generalized Boohner fltering technique is proposed for e two-dimensional unsteady vorticity equation.The generalized stability and convergence are proved strictly.The numerical results are presented.The theoretical analysis in this paper provides a framework for error estimations of such mixed approximation.
