Dynamics of rear stagnant cap formation at the surface of rising bubbles in surfactant solutions at large Reynolds and Marangoni numbers and for slow sorption kinetics

[Display omitted] •Based on a quasi-steady approximation, the theory for decelerated rising of bubbles of a radius of 0.4mm is refined.•The approach is valid for large Marangoni numbers and slow sorption kinetics.•A method for determination of adsorption and desorption rate constants is proposed.•Th...
