替代传统的Smagorinsky模型的动态涡粘性系数的代表性的有限差分法的模型的应用进行了研究。该模型考虑了动态过程中Lij和Mij数值误差的一致性。在Reτ高达590的平面槽道流中验证了所提出的模型,并且发现该模型对离散化测试滤波操作不太敏感。
Alternative representation of the dynamic eddy viscosity coefficient to the traditional Smagorinsky model is investigated for the application of the model to the finite difference method. The model is derived by considering the consistency of the numerical error between Lij and Mij in the dynamic procedure. The proposed model is validated in the plane channel flow at the Reτ of up to 590 and is found to be less sensitive to the discretized test filtering operation.
