开发了一种新型的光纤探头多相流气泡测试系统，可用于气－液两相和气－液－固三相体系中气泡参数的测定。应用此系统研究了三相循环流化床中不同径向位置气泡的上升速度分布、气泡上升速度均值的径向布以及操作条件对这两种分布的影响。
A new type of fiber probe multiphase flow bubble testing system is developed, which can be used to measure bubble parameters in gas-liquid two-phase and gas-liquid-solid three-phase systems. This system was used to study the rising velocity distribution of bubble at different radial positions in three-phase circulating fluidized bed, the radial distribution of mean bubble rising velocity and the influence of operating conditions on these two distributions.
