A windy sea surface with Stokes waves
Nikhil Yewale, Anil Kumar, Vinod Kumar Kadari +1
Predicting the transition of wind-forced, gravito-capillary surface waves from smooth to corrugated states remains a longstanding problem in nonlinear surface wave mechanics. Solvi…
Waves in a shear flow: transition between the KH, Holmboe and Miles instability
Anil Kumar, S. Ravichandran, Ratul Dasgupta
We investigate shear driven wave generation at the interface between two immiscible fluids, using an exponential velocity profile with a sharp density interface representing stable…
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…
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…
