The radial distribution of liquid velocity in the axial direction of a jet bubbling reactor has been measured by experimentation. Three different typical flow structures controlled by liquid jet, gas bubbling, and liquid jet coupled with bubbling are observed. A tank in series model is established on this basis. Calculated values in each region are in good agreement with measured values in jet, bubbling, and wall effect controlled areas. Axial flow rate, radial exchange rate, and jet controlled volume η are analyzed from energy input aspect under different u_g and u_j. Simulation results indicate that under the synergetic action of the liquid jet and gas bubbling effect, jet controlled area exhibits a “spindle” structure, and its size decreases with the increase of u_g. When gas input power occupies about 67% of total energy consumption, the best synergy of liquid jet and gas bubbling is obtained. © 2017 American Institute of Chemical Engineers AIChE J, 64: 1814–1827, 2018

射流鼓泡反应器中的流体力学：实验研究和数学建模

已经通过实验测量了射流鼓泡反应器的轴向上的液体速度的径向分布。观察到三种不同的典型流动结构，这些结构受液体喷射，气体起泡以及液体喷射与起泡控制。在此基础上建立了一个串联坦克模型。每个区域中的计算值与射流，起泡和壁效应控制区域中的测量值高度吻合。从u _g和u _j不同的能量输入角度分析了轴向流量，径向交换率和射流控制量η 。仿真结果表明，在液体射流与气体起泡作用的协同作用下，射流控制区呈现出“纺锤形”结构，其尺寸随u _g的增大而减小。。当气体输入功率约占总能耗的67％时，将获得液体喷射和气体起泡的最佳协同作用。©2017美国化学工程师学会AIChE J，64：1814-1827，2018
