用激光多普勒测速仪和粒子成象测速仪详细测量了气液鼓泡塔内气液并流和气液逆流时的流速分布、湍流度分布和气含率分布，并总结出了湍流度、气含率径向分布关联式。在气含率关联式中，首次考虑了塔高的影响。气泡的存在增强了液相湍动。气液并流时，在升力作用下气泡集聚在塔中心区。气液逆流时，气泡集聚在塔壁面附近。中心速度较大且随着表观气速的增大而增大。塔壁附近出现返混区，零轴向速度和最大湍流度均发生在相对半径ｒ／ Ｒ≈０－７ 左右。
The velocity distribution, turbulence distribution and gas holdup distribution of gas-liquid co-current and gas-liquid countercurrent in gas-liquid bubble column were measured in detail by laser Doppler velocimeter and particle imager. The turbulence and gas Incidence rate radial distribution correlation. In the gas holdup correlation, the effect of tower height was first considered. The presence of bubbles enhances the turbulence of the liquid phase. When gas and liquid flow in parallel, the bubbles accumulate in the central area of the tower under the action of lift. Gas-liquid counter-current, the bubbles gathered in the tower near the wall. The center speed is larger and increases with the increase of superficial gas velocity. The back-mixing zone appears near the wall of the tower. The zero-axial velocity and the maximum turbulence occur at a relative radius r / R≈0-7.
