Focusing of concentric free-surface waves
Lohit Kayal, Vatsal Sanjay, Nikhil Yewale +2
Gravito-capillary waves at free-surfaces are ubiquitous in several natural and industrial processes involving quiescent liquid pools bounded by cylindrical walls. These waves emana…
Jet from a very large, surface-gravity wave
Lohit Kayal, Ratul Dasgupta
We demonstrate that gravity acting alone at large length scales, can produce a jet from a large amplitude, axisymmetric surface deformation imposed on a quiescent, deep pool of liq…
Surface and internal gravity waves on a viscous liquid layer: initial-value problems
Ramana Patibandla, Saswata Basak, Anubhab Roy +1
We study a class of initial value problems (IVPs) involving perturbations on a density stratified, quiescent, viscous liquid layer with a free-surface. The geometry is a two-dimens…
Standing waves and jets on a sessile, incompressible bubble
Yashika Dhote, Anil Kumar, Lohit Kayal +2
We show numerically that large amplitude, \textit{shape deformations}, imposed on a spherical-cap, incompressible, sessile gas bubble pinned on a rigid wall can produce a sharp, wa…
Dimple, jets and self-similarity in nonlinear capillary waves
Lohit Kayal, Saswata Basak, Ratul Dasgupta
Numerical studies of dimple and jet formation from a collapsing cavity often model the initial cavity shape as a truncated sphere, mimicking a bursting bubble. In this study, we pr…
Dynamic stabilisation of Rayleigh-Plateau modes on a liquid cylinder
Sagar Patankar, Saswata Basak, Ratul Dasgupta
We demonstrate dynamic stabilisation of axisymmetric Fourier modes susceptible to the classical Rayleigh-Plateau (RP) instability on a liquid cylinder by subjecting it to a radial…
