Spontaneous superharmonic internal wave generation by modal interactions in uniform and nonuniform stratifications
Dheeraj Varma, Vamsi K. Chalamalla, Manikandan Mathur
Triadic resonance is one mechanism via which internal waves dissipate their energy, often at locations away from their generation sites. In this paper, we perform a combined theore…
Secondary instabilities in the flow past a cylinder: insights from a local stability analysis
Yogesh Jethani, Kamal Kumar, A. Sameen +1
We perform a three-dimensional, short-wavelength stability analysis on the numerically simulated two-dimensional flow past a circular cylinder for Reynolds numbers in the range $50…
Short-wavelength secondary instabilities in homogeneous and stably stratified shear flows
H. M. Aravind, Manikandan Mathur, Thomas Dubos
We present a numerical investigation of three-dimensional, short-wavelength linear instabilities in Kelvin-Helmholtz (KH) vortices in homogeneous and stratified environments. The b…
New wave generation
Matthieu J. Mercier, Denis Martinand, Manikandan Mathur +3
We present the results of a combined experimental and numerical study of the generation of internal waves using the novel internal wave generator design of Gostiaux et al. (2007).…
New (Internal) Wave Generation - Laboratory Experiments
Manikandan Mathur, Matthieu Mercier, Thierry Dauxois +1
In this fluid dynamics video, we demonstrate the experimental generation of various internal wave fields using a novel wave generator. Specifically, uni-directional internal wave b…
Gravity-free hydraulic jumps and metal femtocups
Rama Govindarajan, Manikandan Mathur, Ratul DasGupta +3
Hydraulic jumps created by gravity are seen every day in the kitchen sink. We show that at small scales a circular hydraulic jump can be created in the absence of gravity, by surfa…
