Abstract

Abstract

The bubble velocity was determined in liquid-gas two-phase flow of downflow pipe of LHJ column, using particle dynamics analyzer(PDA) velocimeter.Bubble turbulent velocity distribution on radial and axial direction in downcomer was got first time. It proved that the bubble motion is in violent purbulent pattern in the case of foam flow. The theoretical basis was established to reveal the mechanism of minerization, set up mathematical model and scale up coltnmn.
