## Abstract

This paper concerns the numerical prediction of gas-solid turbulent channel flows using a continuum approach for the dispersed phases. A model, based on separate transport equations for the components of the particle kinetic stress tensor, is briefly presented and the corresponding predictions are compared with large eddy simulation (LES) results. In the LES calculations, particle motion is governed only by drag and the volume fraction of the dispersed phase is assumed to be small enough such that particle-particle collisions and fluid turbulence modulation are negligible. It is shown that the particle kinetic stress transport model gives a satisfactory description for the mechanisms governing the particle velocity fluctuation in the flow: production of the streamwise particle velocity fluctuations by the mean velocity gradient, production of the wall-normal and spanwise velocity fluctuations by the fluid-particle velocity correlations and turbulent transport by the third order particle velocity correlations.
