✦ Synopsis

Equations describing the mean dynamics for two-phase flow exhibit instabilities corresponding to the physical tendency for such flows to be turbulent. Representation of this effect by means of turbulence transport theory converts the mean-flow equations to neutral stability for all perturbation wavenumbers, furnishing a powerful closure constraint for the turbulence transport equations and removing the ill-posed property previously associated with the simplest of the two-phase flow formulations. * This work was performed under the auspices of the United States Department of Energy, and is dedicated to the memory of S. Ulam.

## 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 arbitrary concentration ratios. The Boltzmann equation is appropriate

The work presented here analyses the underlying mechanisms in the continuum equations for non-colliding particles in dilute non-uniform two-phase Β―ows. The study is carried out for axisymmetric particle-laden gas jets, which constitute a good example of non-uniform Β―ow. Equations of radial and axial
