摘要：The Taylor—Couette reactor can achieve precise control of heat transfer,mass transfer,and reactions,and it has been widely used in chemical production fields.In this paper,computational fluid dynamicsdiscrete phase model(CFD-DPM)simulation was used to study the dynamic characteristics of bubbles in the Taylor—Couette reactor,and the results were verified by high-speed camera experiments.The effects of rotational Reynolds number Re,axial Reaand bubble diameter d_(g)were considered.Then a quadratic polynomial model of bubble residence time in the reactor was established using response surface methodology(RSM).The results show that in the range of rotational Re=3482—10446,the movement trajectory of the bubble in the Taylor—Couette reactor followed the cylindrical helix.The increase of rotational Re can strengthen the downflow of Taylor vortex and reduced the ascent rate of bubbles,resulting in the increase of bubble residence time.And there was a synergetic effect of the rotational Re and d_(g)on the residence time.Besides,Re_(a)had positive effect on the bubble residence time under the condition of low level of Re(Re=3482,6964).Finally,the quadratic polynomial model was proven to be feasible to predict the residence time of bubble in the Taylor—Couette reactor.This study contributes to a deeper understanding of the bubble dynamics within Taylor reactors and offers theoretical guidance for their operation.
