项目摘要
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.
为了开发新的不明确区分RANS和LES区域的LES/RANS混合湍流模型,重点关注基于变分多尺度模型的最新模型——时间相关子尺度模型。尽管在湍流通道流中与VMS-LES模型进行比较,但现阶段尚未观察到两个模型之间存在显着差异。但积分点数有待提高,在其他网格模式中也值得研究。
