Abstract
The Burgers' equation is used to model sedimentation of colloidal suspensions in terms of solitary waves. The importance of diffusive terms is highlighted. Analytic expressions are given for the distribution of dispersed material and the wavefront velocities are calculated as functions of time. An explanation of observed sedimentation behaviour is provided along with a discussion of the important features of real sedimenting systems.Keywords
