The study of turbulent properties in stable flexuous blow-suck boundary channel flow
|
Abstract:
In non-equilibrium turbulent flows, the properties between Reynolds stress and rate of strain is different, the phase difference of the Reynolds stress and rate of strain are stable in a sizable range. This is useful to understand Reynolds stress and rate of strain, and posed great problem to non-equilibrium turbulent models and sub-grade Reynolds stress models in LES. Distribution of the disturbance and its non-line term and relation of the phase were also studied with laminar model in this paper.
