| Abstract: | Hybrid RANS/LES strategy is an important method for complex turbulent flow simulations in recent years.A review of the hybrid RANS/LES methodology developed history is presented briefly in this paper,and then three types of hybrid RANS/LES methodologies,which are DES(Detached Eddy Simulation),Menter-SST similar hybrid model and turbulent-spectrum consistent hybrid model respectively,are summarized.The distinguished features and the limitations of these three types of hybrid models are analyzed concisely.Fin... |
