So maybe they are not applicable for dilute partile flows with particle volume fraction < 1e-3. So in this small volume fraction, we do not need to consider the inter-collisions and therefore the kinetic theory model cannot be used. So does it means that in the current version of twoPhaseEulerFoam, we do not have any RAS turbulence models can be used? Anyone has experience with this? best regards, OF
