Computation of turbulent gasparticle suspension flows in channels
Abstract
The mathematical model for gassolid suspensions in turbulent motion, derived from a combination of continuum theory and the Boltzmann statistical method, is applied to the study of a steady, two dimensional motion in a horizontal duct. The numerical methods allowing the solution of the coupled Boltzmann equation and the NavierStokes equations are presented. Finite differencing is used and an implicit scheme is employed. The equations are discretized in the conservation form and the coupled gas and particles equations are solved simultaneously in an interactive manner. The gas equations are solved in a scheme where the pressure gradient is found using a method avoiding iterations. The equation for the particle distribution function is solved using an approximate factored scheme.
