چکیده:

This study is concerned with the two-dimensional gas-solid turbulent plane-mixing layer. The Prandtl’s turbulent model is used for turbulence closure. The solid phase is considered a continuum and a two-fluid model, which is coupled by source terms due to particle drag and particle diffusion. Finite difference scheme has been employed for the governing equations. The effect of particle size and material density is investigated. In addition, it is observed that the loading ratio has no significant effect on the gas-solid flow prediction. The results compared with the existed experimental data’s of others. This kind of modeling will ease the time consuming, stochastic approach of the Eulearian-Lagrangian methods but needs further investigation on the particle diffusivity term.
