Abstract

A two-phase medium composed of air and fine dust or aerosol particles is a relaxing medium, with two relaxing degrees of freedom, corresponding to exchange of momentum and heat between the phases. Model equations for the propagation of weakly nonlinear waves in such a medium are derived, with allowance for finite rates of relaxation. Characteristic features are discussed, in particular the possibility that shock formation may be altogether prevented in some circumstances, and the possibility that shocks that do form may be either fully or partly dispersed.
