Ultrasonic Irradiation (UI) is one of the technologies used to enhance the gas-liquid mass transfer (GLMT) process. Sonophysical effects such as acoustic streaming, jet flow, acoustic fountain, and atomization are the main factors that enhance the mass transfer coefficient. Numerical simulation can provide insight into the complex fluid behaviors under the influence of ultrasound waves such as fluid flow, mixing, cavitation, and mechanism of GLMT. Study on numerical simulation related to high frequency ultrasound waves, particularly on the formation of acoustic fountain and atomization is found to be limited. Recently developed numerical studies of the ultrasonic-assisted GLMT process are reviewed especially on hydrodynamics and mass transfer modeling for varied frequencies of the ultrasound wave. Challenges and future directions on current modeling approaches are analyzed to highlight the potential of numerical modeling of ultrasonic-assisted GLMT phenomena for process design, scale-up, and optimization.

超声波辐照 (UI) 是用于增强气液传质 (GLMT) 过程的技术之一。声流、射流、声喷泉和雾化等声物理效应是提高传质系数的主要因素。数值模拟可以深入了解超声波影响下的复杂流体行为，例如流体流动、混合、空化和 GLMT 机制。与高频超声波有关的数值模拟研究，特别是声喷泉的形成和雾化的研究发现是有限的。最近开发的超声波辅助 GLMT 过程的数值研究，特别是在超声波的不同频率的流体动力学和传质建模方面进行了审查。
