Research Abstract |
In order to develop new LES / RANS hybrid turbulence models that do not clearly distinguish the region of RANS and that of LES, time dependent subscales model which is the latest model based on the variational multiscale models is focused on. Although, in a turbulent channel flow, it is compared with VMS-LES model, significant difference between two models was not observed at this stage. However, the number of integral points should be improved and it also should be studied in the other mesh patterns.
