Velocity of Single Coarse Particle in Two-Phase Gas-Liquid Flows in a Vertical Pipe

Velocity of Single Coarse Particle in Two-Phase Gas-Liquid Flows in a Vertical Pipe

The velocity of single particles in air-water two-phase flows has been investigated. The geometrical shape of the test particles were sphere and cube; their size ranged in volume-equivalent diameter from 4 to 10mm; their density ranged from 1190 to 7850kg/m3. The volumetric fluxes of air and water v...

description The velocity of single particles in air-water two-phase flows has been investigated. The geometrical shape of the test particles were sphere and cube; their size ranged in volume-equivalent diameter from 4 to 10mm; their density ranged from 1190 to 7850kg/m3. The volumetric fluxes of air and water varied within the ranges of 0≤jG
