Role of surfactant-induced Marangoni stresses in drop-interface coalescence

Impact of a microfluidic jet on a pendant droplet

“…The lower average values of U cr for the AOT and Triton solutions can possibly be explained by the Marangoni stresses generated by the flow from areas with low surface tension to those with high surface tension. Indeed, Marangoni stresses have been shown to retard cavity collapse and slow the velocity of Worthington jets 40,41 . Therefore, we can assume that U cr ∝ U γ , indicating that the retraction of the cavity is surface tension driven 42 .…”
