Two-dimensional calculations of stratified turbulent flow in a pipe

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2019
In this paper, we consider the stratified turbulent flow of a two - phase medium in inclined pipes. Based on the new turbulence model [1], a program code for calculating two - dimensional flows for the study of two - phase stratified flows in pipes was ...

Long internal ring waves in a two-layer fluid with an upper-layer current

open access: yesRussian Journal of Earth Sciences, 2020
We consider a two-layer fluid with a depth-dependent upper-layer current (e.g. a river inflow, an exchange flow in a strait, or a wind-generated current).

Large Eddy Simulation of stratified flows over structures

open access: yesEPJ Web of Conferences, 2013
We tested the ability of the LES model CLMM (Charles University Large-Eddy Microscale Model) to model the stratified flow around three dimensional hills.

Settling slurry flow near deposition velocity in inclined pipe of negative slope [PDF]

open access: yesEPJ Web of Conferences, 2019
Pipe flow of sand-water slurry (settling slurry) is sensitive to pipe inclination. The effect of the angle to which the partially stratified flow is inclined from the horizontal has been subject to investigation in numerous studies.

Insights and perspectives on entrainment and detrainment in natural stratified flows

open access: yesApplied Ocean Research
The entrainment hypothesis, first introduced by Taylor and later refined by Turner, has been instrumental in elucidating the mechanisms by which turbulence engulfs ambient fluid.

High-resolution large-eddy simulations of stably stratified flows: application to subkilometer-scale turbulence in the upper troposphere–lower stratosphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Large-eddy simulations of stably stratified flows are carried out and analyzed using the mesoscale atmospheric model Méso-NH for applications to kilometer- and subkilometer-scale turbulence in the in the upper troposphere–lower stratosphere.

Measurement of Interfacial Characteristics of Horizontal and Inclined Oil–Water Flows by Using Wire-Mesh Sensor

open access: yesEnergies, 2022
Oil–water flows are widely encountered in petroleum, chemical, nuclear reactors, and other crucial industrial processes. Due to gravity and interaction between phases, horizontal and inclined oil–water two-phase flows are characterized by remarkable ...

Comparison of dealiasing schemes in large-eddy simulation of neutrally stratified atmospheric flows [PDF]

open access: yesGeoscientific Model Development, 2018
Aliasing errors arise in the multiplication of partial sums, such as those encountered when numerically solving the Navier–Stokes equations, and can be detrimental to the accuracy of a numerical solution.

RANS Modeling of Stably Stratified Turbulent Boundary Layer Flows in OpenFOAM®

open access: yesE3S Web of Conferences, 2015
Quantifying mixing processes relating to the transport of heat, momentum, and scalar quantities of stably stratified turbulent geophysical flows remains a substantial task. In a stably stratified flow, such as the stable atmospheric boundary layer (SABL),

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
