Study on Behavior of Particles in Gas-Liquid-Solid Three-Phase Flow in a Horizontal Pipe

Abstract

The behavior of particles in Gas-Liquid-Solid three-phase flow in a horizontal pipe was experimentally investigated. The behavior of particles was recorded with a high speed video camera and was analyzed with a X-Y coordinator. It was found that particles in a solid-liquid slug section were accelerated and transported. On the other hand, particles in a gas-liquid section remained at the same position. Lift-off angle of particles decreased with increasing the apparent mean velocity of solid-liquid mixtures.But, it increased with increasing the apparent air velocity.
