Internal wave energy flux from density perturbations in nonlinear stratifications
Frank M. Lee, Michael R. Allshouse, Harry L. Swinney +1
Internal gravity wave energy contributes significantly to the energy budget of the oceans, affecting mixing and the thermohaline circulation. Hence it is important to determine the…
Observations of the stratorotational instability in rotating concentric cylinders
Ruy Ibanez, Harry L. Swinney, Bruce Rodenborn
We study the stability of density stratified flow between co-rotating vertical cylinders with rotation rates and radius ratio , where subscripts and…
Internal wave pressure, velocity, and energy flux from density perturbations
Michael R. Allshouse, Frank M. Lee, Philip J. Morrison +1
Determination of energy transport is crucial for understanding the energy budget and fluid circulation in density varying fluids such as the ocean and the atmosphere. However, it i…
Experimental determination of radiated internal wave power without pressure field data
Frank M. Lee, M. S. Paoletti, Harry L. Swinney +1
We present a method to determine, using only velocity field data, the time-averaged energy flux and total radiated power for two-dimensional inter…
Propagating and evanescent internal waves in a deep ocean model
M. S. Paoletti, Harry L. Swinney
We present experimental and computational studies of the propagation of internal waves in a stratified fluid with an exponential density profile that models the deep ocean. The buo…
A Retrospective on Modulated Wavy Vortex Flow
Michael Gorman, Harry Swinney
A fluid dynamics video of the Modulated Wavy Vortex Flow state of Taylor-Couette flow with the outer cylinder fixed is presented. This state precedes the transition to turbulence,…
The Bouncing Jet: A Newtonian Liquid Rebounding off a Free Surface
Matthew Thrasher, Sunghwan Jung, Yee Kwong Pang +2
We find that a liquid jet can bounce off a bath of the same liquid if the bath is moving horizontally with respect to the jet. Previous observations of jets rebounding off a bath (…
Extraction of coherent structures in a rotating turbulent flow experiment
Jori E. Ruppert-Felsot, Olivier Praud, Eran Sharon +1
The discrete wavelet packet transform (DWPT) and discrete wavelet transform (DWT) are used to extract and study the dynamics of coherent structures in a turbulent rotating fluid. T…
Dynamics of drag and force distributions for projectile impact in a granular medium
Massimo Pica Ciamarra, Antonio H. Lara, Andrew T. Lee +3
Our experiments and molecular dynamics simulations on a projectile penetrating a two-dimensional granular medium reveal that the mean deceleration of the projectile is constant and…
Anomalous self-similarity in two-dimensional turbulence
Charles N. Baroud, Brendan B. Plapp, Zhen-Su She +1
Our velocity measurements on a quasi-two-dimensional turbulent flow in a rapidly rotating annulus yield an inverse cascade with E(k)~k^{-2} rather than the expected E(k)~k^{-5/3}.…
