~_ VP0u4CL0【论文摘要】 边界层流动和射流流动是两种典型的剪切流,由于其流动区域是无界的,其稳定性问题的准确数值计算有一些困难。本研究分别采用代数和指数坐标变换结合 Chebyshev 谱配置法对这两种稳定性问题进行求解,可得到了高精度的结果;并发现,对半无界问题代数变换是较好的方法,与 Grosch 和 Orszag 的结论一致,而对无界问题则指数变换较好。

【英文论文摘要】 In this paper some aspects of the numerical computation of the linear temporal hydrodynamic stability of the Blasius boundary layer and Bickely jet are considered.The semi-infinite and infinite domain is mapped to finite domain by algebraic and exponential coordinate transform,and then the solutions are expanded in a finite Chebyshev series.The problem with the boundary condition at infinity is overcome by defining an auxiliary variable,and the matrix eigenvalue problem is attacked directly,it is demonstrated by the Blasius equation and Orr-Sommerfeld equation of flat plane boundary layer that algebraic mappings are very useful if the solution being sought behaves in a simple way at infinity.But for stability equation at infinite domain such as Bickely jet,the exponential mappings is the better without physical constrains.水利论文7}'} I9GH0o9?
