Experimental investigation on free surface vortices driven by tangential inlets [PDF]

open access: yes, 2016
Particle Image Velocimetry (PIV) measurements have been carried out in order to analyze the structure of free surface vortices in a promoting geometry with two tangential inlets. Velocity fields associated to the free surface vortex have been obtained at

Generation of waves at an inertial surface due to explosions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
This paper is concerned with the generation of surface waves by an axially symmetric initial disturbance applied at an inertial surface in an ocean of finite depth.

Velocity Multistability vs. Ergodicity Breaking in a Biased Periodic Potential

open access: yesEntropy, 2022
Multistability, i.e., the coexistence of several attractors for a given set of system parameters, is one of the most important phenomena occurring in dynamical systems.

An Unbiased Estimator of Peculiar Velocity with Gaussian Distributed Errors for Precision Cosmology [PDF]

open access: yes, 2014
We introduce a new estimator of the peculiar velocity of a galaxy or group of galaxies from redshift and distance estimates. This estimator results in peculiar velocity estimates which are statistically unbiased and that have errors that are Gaussian ...

A plane vertical submerged barrier in surface water waves

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
By a simple application of Green's integral theorem, amplitude of the radiated waves at infinity due to a line source in the presence of a fixed vertical plane barrier completely submerged in deep water is obtained.

Eccentricity samples: Implications on the potential and the velocity distribution [PDF]

open access: yesSerbian Astronomical Journal, 2017
Planar and vertical epicycle frequencies and local angular velocity are related to the derivatives up to the second order of the local potential and can be used to test the shape of the potential from stellar disc samples.

On the Determination of the 3D Velocity Field in Terms of Conserved Variables in a Compressible Ocean

open access: yesFluids, 2023
Explicit expressions of the 3D velocity field in terms of the conserved quantities of ideal fluid thermocline theory, namely the Bernoulli function, density, and potential vorticity, are generalised in this paper to a compressible ocean with a realistic ...

Ring source potentials in two superposed fluids separeted by an inertial surface

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
The study of waves at the interface of two superposed fluids due to the presence of a vertical body of revolution requires the consideration of potentials due to horizontal ring sources submerged in one of the fluids.

Velocity-dependent potential effects on two interacting electrons in Cornell quantum dot planted in plasma medium

open access: yesCumhuriyet Science Journal, 2021
In this study, the energy levels of two-electron Cornell quantum dot (TECQD) immersed in Debye and quantum plasma mediums are probed. To model plasma mediums, the more general exponential cosine screened Coulomb (MGECSC) is suggested.
