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…
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…
