【摘要】 提出了一个求解定常Ｅｕｌｅｒ／Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程的计算方法，求解的主管方程是积分形式的Ｅｕｌｅｒ方程或雷诺平均的Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，计算方法是有限体积多步龙格库塔方法，通过在格式中加入自适应的二阶加四阶人工粘性项以保证数值计算的稳定性，用空间变时间步长、焓阻尼来加速定常问题的收敛速度。更多还原

【Abstract】 A numerical method for the Euler or Reynolds-averaged Navier-Stokes equations is presented in the paper, the govern equations are the time-dependent Euler or Reynolds-averaged Navier-Stokes equations in the integral form , the numerical method is Finite Volume multi-stage Runge-Kutta method. An adaptive second order and forth order artificial disspation term has been used for stability, a space varing time stepping method and enthalpy damping for the Euler equations are used to accelerate convergence for steady solution.更多还原
