摘要 该文应用k-ε二方程湍流模型对细长体绕流问题进行数值模拟计算,进而比较湍流模型中湍流参数的设置对计算结果的影响.通过模拟计算得到的湍流强度及粘性比的取值范围有较好的适应性.通过对简单二维剖面进行非定常运动计算,说明了湍流模型参数设置合理,验证了k-ε二方程湍流模型的实用性. The paper applies the turbulence models of k-ε quadratic equation to carry on numerical simulation calculation on the circumfluence problem about the slender body,and then the influences of the setting of turbulence parameters in turbulence models on calculation results are compared.The turbulent intensity and the span of viscosity ratio have better flexibility by simulation calculation.By the nonsteady motion calculation on the two-dimensional section,the paper explains the reasonable preferences of turbulence models and verifies the practicability of the turbulence models.
