MONTE CARLO SIMULATION OF COLLIDING PARTICLES IN GAS-SOLID TURBULENT FLOWS FROM A JOINT FLUID-PARTICLE PDF EQUATION

摘要

This paper is dedicated to Lagrangian approach for modelling particle-particle interactions in gas-solid turbulent flows. This approach is based on a joint fluid-particle pdf equation solved using Monte Carlo method which has been developed to take into account the correlation between colliding particles induced by the fluid. The modification of the turbulence by the particles is not included in the simulations. The Lagrangian results are presented in comparison with LES simulations (Lav-ieville et al., 1995) and continuum model.
