Measurement of Turbulent of Gas-liquid Two-phase Flow in a Bubble Column with a Laser Velocitymenter

摘要：

Turbulent bubbly air/water two-phase up and down flows in bubble column were investigated. Important flow quantities such as local void fraction, liquid velocity and the turbulence intensity were measured using both LDV and PIV. the presence of the bubbles increased the level of turbulence in the flow. Measurements of liquid velocities in bubble columns, of different superficial gas velocities, and of different height, the flow structures show tours vortices and axisymetric flow.
