OSTI ID:6747829
A description of the turbulent flow of a two-phase system is given in terms of a coupled system of Boltzmann and Navier-Stokes equations. The use of a Boltzmann equation for the particle phase makes the description valid for low concentrations. The Boltzmann equation is appropriately modified to account for a velocity-dependent interphase interaction. Within the framework of the Chapman-Enskog expansion, moment equations are derived for the particle phase. The coupled system of moment equations is cast into a form suitable for a statistical description of the turbulent flow.
