In this article, we apply the Vreman model with a dynamic procedure for subgrid scale modeling of turbulent flow and scalar transport under the Lattice Boltzmann framework. Numerical results of two types of typical turbulent flow systems are presented and discussed, i.e., the channel Poiseuille flow with heat transfer, and the Rayleigh-Taylor convection. Due to their intrinsic differences, analyses...
In this article, the Vreman model with a dynamic procedure is applied for subgrid scale modeling of turbulent channel flow and heat transport, under the Lattice Boltzmann framework. Numerical simulations of channel flow at Reτ=180 with a constant temperature difference at the upper and bottom boundaries are presented and verified via comparisons with existing data of direct numerical simulations and...
