综述了粘性液体塔式反应器中的流型、有效剪切速率、液体混合、气含率和气液传质等方面的研究进展。其他新的数据报告的解决方案，甘油，CMC，PAA，和黄原胶在鼓泡塔的直径为0.06，0.14和0.30米的直径。流动行为指数的广泛变化（1至0.18）允许评估由于气体流动引起的有效剪切速率。新的无量纲相关性开发的基础上自己和文献数据，应用于预测KLa发酵液，并与其他反应器类型。
Studies in tower reactors with viscous liquids on flow regime, effective shear rate, liquid mixing, gas holdup and gas/ liquid mass transfer (kLa) are reviewed. Additional new data are reported for solutions of glycerol, CMC, PAA, and xanthan in bubble columns with diameters of 0.06, 0.14 and 0.30 m diameter. The wide variation of the flow behaviour index (1 to 0.18) allows to evaluate the effective shear rate due to the gas flow. New dimensionless correlations are developed based on the own and literature data, applied to predict kLa in fermentation broths, and compared to other reactor types.
