Boltzmann Equation Approach to Two-Phase Flow Turbulence

Abstract

A description of the turbulent flow of 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 is concentrations. The Boltzmann equation is appropriately modified to account for a velocity dependent interphase interaction. Within the framework of 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. Keywords: Random processes; Fluctuations; Inverse powers; Two phase flow.
