SOME ASPECTS OF DILUTE SUSPENSION THEORY

A theory proposed by the author as representative of the flow of a general suspension contains three "interaction forces", f, S and N. For a "quasi-concentrated suspension" and for a "dilute suspension", N and S, N are omitted, respectively. For the latter special case, we treat diffusion of a fluid through an elastic solid. For a "quasi-concentrated suspension", we show that F and S depend on the gradient of the motion gradient. We demonstrate the existence of interesting phenomena: non-simple behavior, dissipative effects, generalized lift and drag forces.
