Gas–Liquid Flow Characteristics and Performance Optimization of Industrial Downfl ow Jet Loop Reactor Based on Computational Fluid Dynamics
Abstract
The fl uid dynamics and structural enhancements of a novel industrial jet loop reactor (JLR) were investigated through Computational
Fluid Dynamics (CFD) simulations. The arc-shaped trajectory of W-shaped baffl e facilitated the continued circulation
of a substantial portion of the fl uid, resulting in increased total gas holdup, axial liquid velocity, and overall liquid circulation
volume. Compared to similar reactors with a round baffl e, the JLR increased gas holdup from 13.01% to 14.04% and liquid
circulation volume from 4.67 m 3 /s to 4.94 m 3 /s; the W-shaped baffl es increased gas holdup and liquid circulation volume by
approximately 8% and 7%, respectively. Additionally, the study explored the infl uence of various structural parameters such
as nozzle diameter, nozzle quantity, draft tube length and shape. Optimal structural parameters were determined based on
this analysis. The insights and design proposed in this work will provide valuable perspectives and further understanding for
reactor scale-up in industrial applications, serving as a guide for geometric and fl ow pattern functionalities.
