摘要

•Local investigations of the gas-liquid mass transfer in microreactors under ultrasonic oscillation.•Ultrasound can significantly affect the gas-liquid hydrodynamics.•Ultrasound can induce a periodic expansion and contraction of the bubble.•Enhancement of gas-liquid mass transfer by ultrasound is more pronounced during bubble flowing than the formation stage.
