| Abstract: | 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 |
