Triads and Rogue Events for Internal Waves in Stratified Fluids with a Constant Buoyancy Frequency

open access: yesJournal of Marine Science and Engineering, 2021
Internal waves in a stratified fluid with a constant buoyancy frequency were studied, with special attention given to rogue modes, extreme waves, dynamical evolution, and Fermi–Pasta–Ulam–Tsingou type recurrence phenomena.

Ellipsoidal vortices in rotating stratified fluids : beyond the quasi-geostrophic approximation

open access: yes, 2015
Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant number EP/H001794/1).We examine the basic properties and stability of isolated vortices having uniform potential vorticity (PV) in a non-hydrostatic ...

Experimental Comparison of Unstratified and Stratified Drag Wakes of a Dimpled Sphere at Reynolds Number 105

open access: yesFluids
The drag wake of a dimpled sphere is studied experimentally using stereo particle image velocimetry at a Reynolds number of 105 in both unstratified and stratified (Froude number ≃80) fluids at downstream distances of 2≤x/D≤15.

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.

A survey of selected aspects of stratified and rotating fluids

open access: yes, 1976
A survey is presented of phenomena in stratified and rotating fluids. Care is taken to define important quantities, to discuss basic concepts, to derive the fundamental equations and to present the basic nondimensional parameters associated with these ...

Penetrative convection in stratified fluids: velocity and temperature measurements [PDF]

open access: yesNonlinear Processes in Geophysics, 2006
The flux through the interface between a mixing layer and a stable layer plays a fundamental role in characterizing and forecasting the quality of water in stratified lakes and in the oceans, and the quality of air in the atmosphere. The evolution of the

Rossby Solitary Waves Generated by Wavy Bottom in Stratified Fluids

open access: yesAdvances in Mechanical Engineering, 2013
Rossby solitary waves generated by a wavy bottom are studied in stratified fluids. From the quasigeostrophic vorticity equation including a wavy bottom and dissipation, by employing perturbation expansions and stretching transforms of time and space, a ...

Effect of Prandtl's ration on balance in geophysical turbulence

open access: yes, 2015
Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant no. EP/H001794/1).The fluid dynamics of the atmosphere and oceans are to a large extent controlled by the slow evolution of a scalar field called ...

On the stability of Rayleigh–Taylor problem for stratified rotating viscoelastic fluids

open access: yesBoundary Value Problems, 2018
We investigate the stability of Rayleigh–Taylor (RT) problem of the stratified incompressible viscoelastic fluids under the rotation and the gravity in a horizontal periodic domain, in which the rotation axis is parallel to the direction of gravity, the ...

Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...
