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。采用此一方程湍流模型分别对扩压器流场以及 ＮＡＳＡ６７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。
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.
