摘要

讨论了求解由单参数Spalart-Allmaras湍流模型封闭的平均Navier-Stokes方程的数值有限体积方法。该方法在HyCFS数值代码框架内实现，并与CFL3D和FUN3D数值代码预测的HyCFS数值解进行了比较验证。考虑了三种验证情况：流过平板的流动、通道内碰撞流动和共流射流。结果表明，所得到的数值解具有较好的一致性。对混合层内的流动速度进行了数值模拟，并与实验结果进行了比较。

Implementation of the Spalart–Allmaras Turbulence Model in a Finite-Volume Gas-Dynamic Solver

A numerical finite-volume method of solving averaged Navier–Stokes equations closed by a one-parameter Spalart–Allmaras turbulence model is discussed. The proposed method is implemented within the framework of the HyCFS numerical code and is verified through comparisons of the HyCFS numerical solutions with those predicted by the CFL3D and FUN3D numerical codes. Three verification cases are considered: flow past a flat plate, bump-in-channel flow, and coflowing jet. It is shown that the numerical solutions obtained are in good agreement with each other. The numerical data on the flow velocity in the mixing layer are compared with experimental results.
