摘要
本文把四阶精度紧致差分格式用于求解超声速、高超声速三维边界层稳定性问题。提出了适用于求解高速边界层特征值问题的 Chebyshev 多项式配置点方法,并将各种数值方法进行了比较。数值结果表明上述两种方法是求解高速三维边界层稳定性问题的有效数值方法。
A fourth order accurate two point compact difference scheme is used for stability analysis of hypersonic 3 D boundary layer.An improving Chebyshev spectral collocation scheme is developed.It is suitable for solving eigenvalue problem of high speed boundary layer.Various numerical methods for the solution of linear stability equations for compressible boundary layers are compared.The numerical result indicats that the two numerical methods above mentioned are efficient for solving the compressible linear stability problem
