Flow Invariance on Stratified Domains [PDF]

open access: yesSet-Valued and Variational Analysis, 2013
This paper studies conditions for invariance of dynamical systems on stratified do- mains as originally introduced by Bressan and Hong. We establish Hamiltonian conditions for both weak and strong invariance of trajectories on systems with non-Lipschitz data.

Water Tank Experiments on Stratified Flow over Double Mountain-Shaped Obstacles at High-Reynolds Number

open access: yesAtmosphere, 2017
In this article, we present an overview of the HyIV-CNRS-SecORo (Hydralab IV-CNRS-Secondary Orography and Rotors Experiments) laboratory experiments carried out in the CNRM (Centre National de Recherches Météorologiques) large stratified water flume. The

Numerical simulation of stratified flows usingOpenFOAM package

open access: yesТруды Института системного программирования РАН, 2018
The paper is devoted to construction of a numerical model and computations of continuously stratified fluid flows in field of external mass forces accounting for dissipative factors, viscosity and diffusion. Mathematical model is based on the fundamental

Numerical modeling of horizontal stratified two-phase flows using the AIAD model

open access: yesFrontiers in Energy Research, 2022
In nuclear reactor safety research, the countercurrent gas-liquid two-phase flow in the hot leg of a pressurized water reactor (PWR) has attracted considerable attention.

Dissipation rate of turbulent kinetic energy in stably stratified sheared flows [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Over the years, the problem of dissipation rate of turbulent kinetic energy (TKE) in stable stratification remained unclear because of the practical impossibility to directly measure the process of dissipation that takes place at the smallest scales of ...

Horizontal Stratified Air–Foam–Water Flows: Preliminary Modelling Attempts with OLGA

open access: yesFluids, 2023
Water accumulation is a major problem in the flow assurance of gas pipelines. To limit liquid loading issues, deliquification by means of surfactant injection is a promising alternative to the consolidated mechanical methods.

Small-Scale Anisotropy in Stably Stratified Turbulence; Inferences Based on Katabatic Flows

open access: yesAtmosphere, 2023
The focus of the current study is on the anisotropy of stably stratified turbulence that is not only limited to large scales and an inertial subrange but also penetrates to small-scale turbulence in the viscous/dissipation subrange on the order of the ...

Stratified Sadovskii flow in a channel [PDF]

open access: yesJournal of Fluid Mechanics, 1993
Stably stratified and non-stratified flows past a touching pair of vortices with continuous velocity are considered. An asymptotic solution for the very long eddies is determined. Numerical results cover the whole range of subcritical stratification and eddy length.

Propagation of Rossby waves in stratified shear flows

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
A study is made of the propagation of Rossby waves in a stably stratified shear flows. The wave equation for the Rossby waves is derived in an isothermal atmosphere on a beta plane in the presence of a latitudinally sheared zonal flow.

Periodic Flows in a Viscous Stratified Fluid in a Homogeneous Gravitational Field

open access: yesMathematics, 2023
The density of a fluid or gas, which depends on the temperature, pressure and concentration of dissolved substances or suspended particles, changes under the influence of a large number of physical factors.
