Abstract: The gas hold-up characteristics of a downflow liquid jet loop reactor were studied with Newtonian and non-Newtonian fluids. The optimum ratio of draft tube to reactor diameter was found to be about 0.57. A theoretical model was obtained by solving the equation of motion. The prediction of gas holdup with the model agreed with the experimental data. These results could be useful for design and scale-up purposes.

摘要： 本文从奈维—斯托克斯运动方程出发,结合体系特性及反应器内流体流动状况,建立了计算下喷式环流反应器气含率的模型方程式,并依实验结果确立了模型参数.该模型方程式适用于牛顿型与非牛顿型流体体系.
