Azimuthal Instability in Oscillating Liquid Jets by the Weber Number Variations
Hyoungwoo Kim, Seungwon Shin, Hyosang Yoon +2
This paper investigates the dependence of azimuthal mode growth rate of oscillating liquid laminar jets on the Weber number. The oscillating liquid laminar jets were simulated over…
Numerical simulation of a two-frequency-driven superlattice Faraday-wave pattern
Debashis Panda, Nicolas Périnet, Abdullah M. Abdal +6
The formation of a superlattice pattern in two-frequency-driven Faraday waves discovered and named SSS-I by Arbell & Fineberg (1998, 2002) is investigated by means of Direct Numeri…
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…
Surfactant-laden bubble bursting: dynamics of capillary waves and Worthington jet at large Bond number
Paula Pico, Lyes Kahouadji, Seungwon Shin +3
We present a numerical study of the main sub-stages preceding aerosol formation via bursting bubbles: capillary wave propagation along the bubble, convergence at the bubble's apex,…
Drop encapsulation and bubble bursting in surfactant-laden flows in capillary channels
Paula Pico, Lyes Kahouadji, Seungwon Shin +3
We present a parametric study of the unsteady phenomena associated with the flow of elongated gas bubbles travelling through liquid-filled square capillaries under high Weber numbe…

We examine the time-dependent flow dynamics inside an idealised renal pelvis in the context of a surgical procedure for kidney stone removal, extending previous work by Williams et…
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…
The transition to aeration in two-phase mixing in stirred vessels
Lyes Kahouadji, Assen Batchvarov, Cristian R. Constante Amores +5
We consider the mixing of a viscous fluid by the rotation of a pitched blade turbine inside an open, cylindrical tank, with air as the lighter fluid above. To examine the flow and…
Three-dimensional dynamics of falling films in the presence of insoluble surfactants
Assen Batchvarov, Lyes Kahouadji, Cristian R. Constante-Amores +5
