Abstract

The dynamic mixed subgrid-scale model of Zang et al. (DMM1) is modified with respect to the incorporation of the similarity model in order to remove a mathematical inconsistency. Compared to DMM1, the magnitude of the dynamic model coefficient of the modified model (DMM2) is increased considerably, while it is still significantly smaller than as occurs in the dynamic subgrid-scale eddy-viscosity model of Germano (DSM). Large eddy simulations (LES) based on DMM1 gives a significant improvement over LES using DSM, while even better agreement is achieved with DMM2.
