Ultra-relativistic geometrical shock dynamics and vorticity
, 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 ...

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

Variational Principles for Stochastic Fluid Dynamics
, 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.

Cerebrospinal fluid dynamics along the optic nerve
Frontiers 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.

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

Is the Kelvin Theorem Valid for High-Reynolds-Number Turbulence? [PDF]
, 2006 The Kelvin-Helmholtz theorem on conservation of circulations is supposed to hold for ideal inviscid fluids and is believed to be play a crucial role in turbulent phenomena, such as production of dissipation by vortex line-stretching.

Intermittency of Velocity Circulation in Quantum Turbulence
Physical Review X, 2021 The velocity circulation, a measure of the rotation of a fluid within a closed path, is a fundamental observable in classical and quantum flows. It is indeed a Lagrangian invariant in inviscid classical fluids. In quantum flows, circulation is quantized,

Hamilton's principle for quasigeostrophic motion
, 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 ...
