Wave Propagation in Mixtures of Solids and Liquids

Abstract

The differential equations for conservation of mass and linear momentum in unsteady flows of slurries are developed to the point where they can be solved using the numerical method of characteristics. An approximation is introduced which permits the flow velocities of the two components to vary at different rates. Comparisons are made with new experimental data for the amplitude and speed of propagation of transient pressure waves in slurries containing up to 40 per cent by volume of solid matter.
