| 摘 要： | 本文将Spalart-Allmaras湍流模型方程推导为守恒形式,并应用于内流湍流流场计算.采用此-方程湍流模型分别对扩压器流场以及NASA 67转子流场进行了数值模拟.结果表明常用在外流计算中的Spalart-Allmaras湍流模型在内流计算中仍具有较高的精度、数值稳定性和效率.

| Abstract: | The original Spalart-Allmaras one-equation turbulence model is casted into conservative form, and has been used in the numerical simulations of internal flows. Two type of internal flows, i.e., a diffuser flow and NASA rotor 67 transonic flow, are investigated with Spalart-Allmaras turbulence model. It is shown that Spalart-Allmaras turbulence model which is usually used in external flows still sustains its precision, numerical stability and efficiency in the calculations of internal flows. |
