摘要
文中讨论了雷诺平均Navier-Stokes(RANS)方程组与湍流模型方程的统一求解技术。在有限体积方法框架下,采用迎风格式进行空间离散,时间推进则分别采用显式Runge-Kutta方法和LU-SGS隐式推进方法。通过数值模拟NACA0012和RAE2822翼型的跨音速流场,对文中方法进行了验证。
With the numerical solution of RANS equations,the applications of B-L zero equation and k-ε/k-ωtwo-equa- tions turbulence models are discussed in this paper.On the basis of a finite volume method,the explicit four-stage Runge-Kutta method and the LU-SGS implicit scheme are applied for obtaining steady-state solutions for the two-dimen- sional cases.
