Dynamics of retracting surfactant-laden ligaments at intermediate Ohnesorge number

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

“…These observations also agree with the recent studies reported by Constante-Amores et al. (2020) and Constante-Amores et al. (2021) in terms of the escape of capillary singularity during the capillary retraction of a liquid thread, and the inhibition of jet-drop formation from bursting bubbles, respectively.…”

“…(2020) and Constante-Amores et al. (2020) suggested that the investigated interfacial dynamics reaches saturation above ; thus, the selected interfacial Péclet is set to . In terms of the chosen bulk Péclet number, Agrawal & Neuman (1988) suggested that the interfacial and bulk Péclet numbers are of the same order of magnitude; on this basis, hereafter, we set .…”

“…Recently, Constante-Amores et al. (2020) and Kamat et al. (2020) showed the deleterious effect of Marangoni stresses on interfacial singularities in the context of the inhibition of the end-pinching mechanism during the capillary retraction of a liquid thread.…”

Direct numerical simulations of transient turbulent jets: vortex-interface interactions

“…As shown recently by Constante-Amores et al. (2020), surfactants are capable of inhibiting capillary singularities and rigidifying the interface, subsequently changing the fate of the atomisation. Hence, the presence of surfactants may change the present results, providing us with an exciting avenue of future research.…”

“…These phenomena include breakup and recoiling of liquid threads (Constante-Amores et al. 2020), falling film flows (Batchvarov et al. 2020 a ), propagation of elongated bubbles in channels (Batchvarov et al.…”
