| 摘 要： | 选择了6个有代表性的湍流模型,对超声速燃烧湍流流场开展了数值模拟.采用的模型包括5个线性涡粘性模型和1个非线性模型,在非线性模型中同时引入了可压缩修正.数值结果表明,本文发展的数值方法可以成功地应用于求解可压缩、含化学反应的多组分N-S方程.同时引入可压缩性修正的二阶涡粘性模型给出的结果较好.

| Abstract: | The turbulent flow field of supersonic combustion is numerically simulated with application of six typical turbulence models.They include five linear eddy-viscosity models and a nonlinear model,in which the compressibility modification is considered.The numerical results show that the present numerical approach can successfully solve Navier-Stokes equation for the compressible,multi-species fluid with chemical reactions.The performance of the nonlinear model with compressibility modification is better. |
