Jet coronation: Coexistence of compressible and incompressible dynamics
H. Watanabe, K. Hashimoto, W. K. A. Worby +4
This paper is associated with a poster winner of a 2025 American Physical Society's Division of Fluid Dynamics (DFD) Gallery of Fluid Motion Award for work presented at the DFD Gal…
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…
Marangoni-driven patterns, ridges, and hills in surfactant-covered parametric surface waves
Debashis Panda, Lyes Kahouadji, Laurette Tuckerman +4
Parametric oscillations of an interface separating two fluid phases create nonlinear surface waves, called Faraday waves, which organise into simple patterns, like squares and hexa…
