Interfacial standing wave-patterns disentangle dilatational and shear surface viscous effects
Debashis Panda, Abdullah M. Abdal, Mosayeb Shams +5
Dilatational and shear surface viscosities are highly correlated parameters, making their individual contributions difficult to disentangle in Stokes flow, linearised flow models,…
Direct numerical simulation of two-phase flows with surfactant-induced surface viscous effects
Debashis Panda, Seungwon Shin, Abdullah M. Abdal +4
Direct numerical simulations of interfacial flows with surfactant-induced complexities involving surface viscous stresses are performed within the framework of the Level Contour Re…
Direct numerical simulations of transient turbulent jets: vortex-interface interactions
Cristian R. Constante-Amores, Lyes Kahouadji, Assen Batchvarov +4
The breakup of an interface into a cascade of droplets and their subsequent coalescence is a generic problem of central importance to a large number of industrial settings such as…
Three-dimensional dynamics of falling films in the presence of insoluble surfactants
Assen Batchvarov, Lyes Kahouadji, Cristian R. Constante-Amores +5
We study the effect of insoluble surfactants on the wave dynamics of vertically-falling liquid films. We use three-dimensional numerical simulations and employ a hybrid interface-t…
Effect of surfactant on elongated bubbles in capillary tubes at high Reynolds number
Assen Batchvarov, Lyes Kahouadji, Mirco Magnini +6
The effect of surfactants on the tail and film dynamics of elongated gas bubbles propagating through circular capillary tubes is investigated by means of an extensive three-dimensi…
Dynamics of a surfactant-laden bubble bursting through an interface
C. R. Constante-Amores, L. Kahouadji, A. Batchvarov +4
We study the effect of surfactant on the dynamics of a bubble bursting through an interface. We perform fully three-dimensional direct numerical simulations using a hybrid interfac…
