Swirling fluid flow in flexible, expandable elastic tubes: variational approach, reductions and integrability [PDF]

open access: yes, 2019
Many engineering and physiological applications deal with situations when a fluid is moving in flexible tubes with elastic walls. In the real-life applications like blood flow, there is often an additional complexity of vorticity being present in the ...

Material derivatives of higher dimension in geophysical fluid dynamics

open access: yesMeteorologische Zeitschrift, 2004
The familiar operator D/Dt in fluid dynamics defines the material derivative for a fluid particle with dimension zero. In this paper we define and use "macroscopic" or multidimensional material derivatives D1/Dt, D2/Dt and D3/Dt.

Dynamics of the solar tachocline I: an incompressible study [PDF]

open access: yes, 2001
Gough & McIntyre have suggested that the dynamics of the solar tachocline are dominated by the advection-diffusion balance between the differential rotation, a large-scale primordial field and baroclinicly driven meridional motions.

Higher order dynamic mode decomposition beyond aerospace engineering

open access: yesResults in Engineering, 2023
It is a well known fact that fluid dynamics play a crucial rule in countless fields in scientific and industrial applications, including nature and medicine (ocean currents, fluid motion around jellyfish, blood circulation...), in energy production (wind

Variational Principles for Stochastic Fluid Dynamics

open access: yes, 2015
This paper derives stochastic partial differential equations (SPDEs) for fluid dynamics from a stochastic variational principle (SVP). The Legendre transform of the Lagrangian formulation of these SPDEs yields their Lie-Poisson Hamiltonian form.

Ultra-relativistic geometrical shock dynamics and vorticity

open access: yes, 2007
Geometrical shock dynamics, also called CCW theory, yields approximate equations for shock propagation in which only the conditions at the shock appear explicitly; the post-shock flow is presumed approximately uniform and enters implicitly via a Riemann ...

Atmospheric Circulation and Tides of "51Peg b-like" Planets [PDF]

open access: yes, 2002
We examine the properties of the atmospheres of extrasolar giant planets at orbital distances smaller than 0.1 AU from their stars. We show that these ``51Peg b-like'' planets are rapidly synchronized by tidal interactions, but that small departures from

Cerebrospinal fluid dynamics along the optic nerve

open access: yesFrontiers in Neurology, 2022
The cerebrospinal fluid (CSF) plays an important role in delivering nutrients and eliminating the metabolic wastes of the central nervous system. An interrupted CSF flow could cause disorders of the brain and eyes such as Alzheimer's disease and glaucoma.

Hamilton's principle for quasigeostrophic motion

open access: yes, 1998
We show that the equation of quasigeostrophic (QG) potential vorticity conservation in geophysical fluid dynamics follows from Hamilton's principle for stationary variations of an action for geodesic motion in the f-plane case or its prolongation in the ...
