Two index-matched systems of solid particles in liquid have been developed to enable the study of velocity and concentration distributions in the highly concentrated solid-liquid flows. The mixtures have excellent optical transparency up to depths exceeding 80 mm at concentrations up to 50% solids by volume. Highly visible marker particles with nearly the same mechanical properties as the index-matched particles are formed by metal plating or substitution. Good quality images of marker particles are obtained in both stationary and moving two-phase mixtures, and permit accurate tracking of the individual markers.
