In this study, the gas–liquid hydrodynamics in a self-suction jet reactor with or without swirling addition design are investigated both experimentally and numerically. The experimental results are characterized by the gas suction rate and gas volume fraction. The Eulerian approach is used to analyze the hydrodynamics of two phases. The experimental results show that the gas suction rate with swirling addition is much larger than that without swirl. The numerical predictions indicate that due to the existence of centrifugal force, the swirling addition leads to the generation of radial pressure gradient, which pushes the gas towards the center of the pipe and liquid to the vicinity of the wall, resulting in effective mixing of two phases. Moreover, the liquid flow rate and swirling intensity should be well selected to balance the gas suction rate and the final gas–liquid dispersion efficiency for the fixed jet reactor configuration with swirling addition.
