文摘

A deeper understanding of a zigzagging bubble's mass transfer process was gained. Visualized CO2 dissolution process via a LIF method from two orthogonal directions. The LIF results were calibrated via a photoelectric optical fiber probe. We discuss the direction of the Marangoni convection by force analysis. Influences of the Marangoni effect on instantaneous mass transfer are discussed.
