Spalart和Allmaras湍流模型已用隐式有限差分技术在有限体积程序中实现。为了验证该方法的有效性，对各种湍流进行了数值计算，并给出了数值结果。特别关注高超声速的应用。考虑了高超声速风洞绕流、中空圆柱耀斑上的马赫数为5的流动和双曲面耀斑上的马赫数为6.8的绕流。数值计算结果与实验数据的临界比较，为评价高速流动模拟中的模型行为提供了有用的依据。
The Spalart and Allmaras turbulence model has been implemented in a finite volume code using an implicit finite difference technique. A wide range of turbulent flows have been computed to validate the implementation and numerical results are shown. A special attention is paid to hypersonic applications. A hypersonic wind tunnel flow, a Mach 5 flow over a hollowcylinder-flare and a Mach 6.8 flow over a hyperboloidflare have been considered. The critical comparison between the numerical results and experimental data has given useful elements to evaluate the model behaviour in high speed flow modeling.
