LDV Measurements in a Centrifugal Slurry Pump: Water and Dilute Slurry Flows

A two-component LDV system was used to investigate single and two-phase flow in a representative section at the impeller outlet of a centrifugal slurry pump. Measurements were performed at Q n and 0.5 Q n with water and dilute slurry flows (C=0.04 and 0.16 percent by volume). The solids consists of 0.8 mm glass beads. Particle Reynolds number is 65. The point liquid and solid velocities were determined with a Doppler signal amplitude discrimination approach
