A windy sea surface with Stokes waves
Nikhil Yewale, Anil Kumar, Vinod Kadari +1
Predicting the transition of wind-forced, gravito-capillary surface waves from smooth to corrugated states remains a longstanding problem in nonlinear wave mechanics. Solving drive…
Interfacial waves from pressure forcing: revisiting classical theories from an IVP perspective
Vinod Kumar Kadari, Nikhil Yewale, Palas Kumar Farsoiya +2
A localised overpressure translating at a uniform speed greater than a critical value acts at the interface between two deep fluid layers with different densities. We analyse the r…
Free oscillations of a standing surface wave and its mechanical analogue
Nikhil Yewale, Sakir Amiroudine, Ratul Dasgupta
We present an analogy between natural oscillations of the standing wave type on a pool of liquid with an interface and a mechanical oscillator model. It is shown that the equations…
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…
