Abstract
This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solidboundary layer flow using a fully Eulerian two-fluid model. The closures required for equationsdescribing the particulate phase are derived from the kinetic theory of granular flows. Gas phaseturbulence is modeled by one-equation model and solid phase turbulence by MLH theory. Resultsof one-way and two-way coupled approaches are compared with the available experimental andnumerical results. Results show that one-way coupled approach is more efficient for particulatevelocity prediction in dilute flows. But, if the gas-phase flow characteristics are desired, the twowaycoupled approach should be used. Effects of free stream velocity on the coupling arediscussed.
