Study of the parametric dependence of erosion wear for the parallel flow of solid-liquid mixtures

The phenomenon of erosion wear due to the cutting action of solid particles in solid-liquid mixture flows has been studied in a slurry pot tester. Special fixtures and design modifications were incorporated in a slurry pot tester in order to ensure that the erosive wear on the wear piece is primarily due to parallel flow of the mixture. Experiments performed at various solid concentrations, particle sizes and velocities, show that the parallel flow wear increases with increase in solid concentration, particle size and velocity. The parametric dependence on velocity is comparatively much stronger as compared to that on either solid concentration or particle size. (C) 1999 Elsevier Science Ltd. All rights reserved.
