Kelvin-Wave Cascade and Decay of Superfluid Turbulence
Kelvin wave distortion vortex line cryogenic superfluid turbulence dynamics
2014/12/20
Kelvin waves (kelvons), the distortion waves on vortex lines, play a key part in the relaxation of superfluid turbulence at low temperatures. We present a weak-turbulence theory of kelvons. We show th...
Scale-Separation Scheme for Simulating Superfluid Turbulence: Kelvin-Wave Cascade
Kelvin from the distorted wave of vortex superfluid turbulence low temperature the numerical simulation of vortex line
2014/12/20
A Kolmogorov-type cascade of Kelvin waves—the distortion waves on vortex lines—plays a key part in the relaxation of superfluid turbulence at low temperatures. We propose an efficient numeric scheme f...

Vorticity quantitative long wave physics super fluid turbulent flow the vortex line
2014/12/19
As long as vorticity quantization remains irrelevant for long-wave physics, superfluid turbulence supports a regime macroscopically identical to the Kolmogorov cascade of a normal liquid. At high enou...

2014/12/18
Direct numeric simulation of the Biot-Savart equation readily resolves the 17/5 spectrum of the Kelvin-wave cascade from the 11/3 spectrum of the non-local (in the wavenumber space) cascade scenario b...

We derive a type of kinetic equation for Kelvin waves on quantized vortex filaments with random large-scale curvature, that describes step-by-step (local) energy cascade over scales caused by 4-wave i...
We study two different types of simplified models for Kelvin wave turbulence on quantized vortex lines in superfluids near zero temperature. Our first model is obtained from a truncated expansion of t...

2009/2/16
Using the method of strained coordinates, a uniformly valid approximation to the nonlinear equatorial Kelvin wave is derived. It is shown that nonlinear effects are negligible for the Kelvin waves ass...

2009/2/6
Free Kelvin wave solutions of the linear shallow-water equations are described, for an f-plane. Lateral and vertical viscous effects are represented by terms ν2u and du, respectively, where (u,v) is t...

Free Kelvin Wave Finite-Difference Numerical Models
2009/2/6
The effects of viscosity and finite- differencing on free Kelvin waves in numerical models (which employ the Arakawa B- or C-grid difference schemes) are investigated using the f-plane shallow-water e...
Interior Reflections of a Periodically Forced Equatorial Kelvin Wave

2009/1/16
A fully three-dimensional, wind-forced equatorial model is used to study the effects of the strong near- surface equatorial pycnocline on energy transmission into the deep ocean. The equatorial Kelvin...

Coastally trapped Kelvin waves in a model system of a flat half-planar ocean with a high-drag region of width L adjacent to the coast have properties that depend on L, and its drag, D0. For L less tha...

A numerical model is designed to study the effects of the strong, near-surface associated with the equatorial current system on energy transmission of time-periodic equatorial waves into the deep mean...

We consider the problem of a low-frequency, two-layer, coastal Kelvin wave which impinges on a topographic ridge or valley at some angle to the coastline, with the aim of bounding the transmission of ...

This paper considers the interaction between a bottom-trapped low-frequency, reduced-gravity maid Kelvin wave propagating along a coastal wall, and a smooth ridge extending away from the coastline. Al...
