Abstract

Model of the smoothed motion of interacting particles in LES of turbulent dispersed twophase channel flow M. Gorokhovski & A. Chtab COMA UMR-6614 CNRS University of Rouen, France Abstract By analogy with kinetic approach, the gas-solid turbulent flow was considered as an ensemble of interacting both stochastic liquid and solid particles, and then the motion equation for the solid particle along a partially averaged trajectory has been derived. Pushing further this analogy with kinetic approach, the statistical temperature has been introduced for both the solid particle and for the stochastic liquid particle with relaxation-type relation between these two "temperatures". The smoothed particles dynamics was then computed along LES of turbulent channel gas flow with "two-way" coupling of momentum. The calculated results are compared with the experiment of Kulick et. al. (1994) and with the devoted to this experiment LESIparticle computation of Yamomoto et. al. (2001), where the inter-particle int
