Application of phase difference technique in the measurement of velocity, concentration and particle size in liquid-solid flow

Abstract

Some preliminar simultaneous measurements of one component of the velocity, of diameters and of concentration of spherical glass particles in water by phase difference technique are presented. The measurements concern a settling tank model; since recirculating flow zone exists in the tank, a double Bragg cell, in order to discriminate the velocity sense is used.Some preliminar simultaneous measurements of one component of the velocity, of diameters and of concentration of spherical glass particles in water by phase difference technique are presented.
