Mixture Equations

Abstract

At each point x and at each time t, the agglomeration of configurations of B _k forms a composite body B. However, it is useful to construct the body from the viewpoint of physical motivation, because it is the entity most easily observed and measured with conventional instruments. For example, much of the older work on the rheometry of suspensions [24] is based on measurements of B alone. It is also convenient to construct B from the viewpoint of mathematics, principally because boundary conditions are often more easily stated or understood in terms of B than in terms of B _k .
