文摘

Cost efficient extended Langevin subgrid-scale model for the dispersed phase. Large eddy simulations of turbulent bubble-laden and particle-laden flows. Wall-bounded turbulent flows in vertical channels at different Re and St. Minor influence on mean velocity and velocity fluctuations but on volume fraction. Influence of particle Stokes number on the effect of the Langevin model.
