Transformation of the Peregrine Breather Into Gray Solitons on a Vertically Sheared Current

open access: yesFrontiers in Physics, 2021
In this Brief Research Report, we show, within the framework of the nonlinear Schrödinger equation in deep water and in the presence of vorticity (vor-NLS), that the Peregrine breather traveling at the free surface of a shear current of slowly varying ...

On The Effect of Flow Direction on Mixed Convection Around Heated Circular Cylinder [PDF]

open access: yesEngineering and Technology Journal, 2009
A numerical investigation of laminar mixed convection around horizontal isothermalcylinder is presented. The free stream direction varies between the vertically upward(assisting flow) and vertically downward (opposing flow).

Lagrangian solutions to the 2D euler system with L^1 vorticity and infinite energy [PDF]

open access: yes, 2015
We consider solutions to the two-dimensional incompressible Euler system with only integrable vorticity, thus with possibly locally infinite energy.

Extremely Low Frequency (0.1 to 1.0 mHz) Surf Zone Currents

open access: yesGeophysical Research Letters, 2019
Low‐frequency surf zone eddies disperse material between the shoreline and the continental shelf, and velocity fluctuations with frequencies as low as a few mHz have been observed previously on several beaches.

Effects of Abrupt Cross-Section Area Change on theMultiparameter Propagation Characteristics of Premixed Methane–Air Explosion in Pipes

open access: yesApplied Sciences, 2023
This paper explores the effects of an abrupt cross-section area change of gas pipes on the propagation law of explosion. For this, an explosion pipe experimental system was established, and a numerical research was conducted.

Evidence for enhanced primary production resulting from relative vorticity induced upwelling in the Catalan Current

open access: yesScientia Marina, 2004
In baroclinic fronts, jets and eddies, potential vorticity, P = (V + f) / D, connects horizontal motions of planetary vorticity, f, and relative vorticity, V, to vertical transport through increases and decreases of the water column height, D.

Multi-vortices are wall vortices: A numerical proof [PDF]

open access: yesNuclear Physics B, 2006
We study the Abrikosov-Nielsen-Olesen multi-vortices. Using a numerical code we are able to solve the vortex equations with winding number up to n=25,000. We can thus check the wall vortex conjecture previously made in hep-th/0507273 and hep-th/0507286. The numerical results show a remarkable agreement with the theoretical predictions.

The baroclinic secondary instability of the two-dimensional shear layer [PDF]

open access: yes, 2000
The focus of this study is on the numerical investigation of two-dimensional, isovolume, high Reynolds and Froude numbers, variable-density mixing layers. Lagrangian simulations, of both the temporal and the spatial models, are performed. They reveal the
