| 摘 要： | 利用三维雷诺平均的Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，采用к－ε湍流模式，运用有限体积法，对某捆绑了４个助推器的大型运载火箭进行了计算，得到了火箭在亚、跨、超间速范围内的真实复杂流场所动特性。数值结果较好地反映了芯级和助推器之间的气动干扰状况。

| Abstract: | A three-dimensional Reynolds averaged Navier-Stokes solver is applied to analyze the aerodynamic behavior of rocket with four boosters. The model employs the K--e model and relies on a finite volume method exploits grid refinement. A large amount of data have been attained describing the aerodynamic behavior of the configuration. The data reflects the interaction of a boundary layer on the rocket surface with a bow shock by the booster. |
