摘要：
The classical approach to performing large eddy simulations of turbulent flows is to employ in the governing equations subgrid scale models based on eddy viscosity concepts. The development of the similarity model about 30 years ago led to the realisation that subgrid scale models that do not use eddy viscosity concepts are possible and have many desirable properties. In this article, we review modelling approaches belonging to this category and discuss their advantages and the limitations.
