When the second derivative of the bubble number in unit bed volume with respect to gas velocity equals zero, the flow regime transition occurs. The model fits fairly well with the experimental data.
导出了当单位床层体积中气泡数目对气速的二阶导数为零时发生流型转变，该模型的计算机结果与实验数据吻合良好。
A dispersed bubble flow regime results in more even flow patterns, increasing the amount of liquid that can be upgraded in a single reactor.
分散的鼓泡流型导致更均匀的流型，增加了能够在单一反应器中进行改质的液体量。
The liquid recirculating reactor of this invention employs a dispersed bubble flow regime, which requires a high liquid to gas ratio.
本发明的液体再循环反应器使用分散的鼓泡流型，这需要高液气比。
