✦ Synopsis

When

a nondilute multicomponent fluid is placed in a viscometric testing device, the flow that is produced is not a viscometric flow. Rather, relatively thin layers of fluid with relatively few suspended particles accumulate near the boundaries. These layers exhibit high shear rates. The suspended particles accumulate far away from the boundaries, giving a high local viscosity and a low shear rate. We consider a simple but properly invariant theory of multicomponent fluids. We investigate steady flow between parallel plates with one plate stationary and the other plate moving parallel to it at constant speed. We give exact solutions to the field equations
