"A Mixture Theory Formulation for Solids Transport"


ABSTRACT


We discuss the importance of constitutive modeling of the stress tensors in solids transport. We first give a brief account of the formulation of a two-component Mixture Theory where the mixture consists of a linearly viscous fluid infused with solid particles. The solid particles are modeled as a granular media and it is assumed that the mixture is dense enough so that we can use the theory of interacting continua. The subsequent boundary value problem, flow between two flat plates, is then solved numerically and results for various dimensionless numbers are presented for velocities and volume fraction profiles.
