Intermittency of Velocity Circulation in Quantum Turbulence [PDF]
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,

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.

Computational fluid dynamics prediction and validation of gas circulation in a cheese-ripening room [PDF]
International Dairy Journal, 2005 This paper discusses the application of a computational fluid dynamics (CFD) approach to predicting air velocity patterns and circulation of an exogenous gas inside a pilot cheese-ripening room in 3 dimensions (3D). Comparison of numerical results with experimental data showed a fairly close agreement in the qualitative prediction and a few ...

Crustal dynamics of Mount Vesuvius from 1998 to 2005: Effects on seismicity and fluid circulation [PDF]
Journal of Geophysical Research: Solid Earth, 2008 This paper presents the results of hydrogeochemical and seismological studies carried out at Mount Vesuvius during the period June 1998 to December 2005. Hydrogeochemical data show the occurrence of slowly varying long‐term variations in the total dissolved salts and bicarbonate contents of the groundwaters, accompanied by a general decline in water ...

Cell-Driven Fluid Dynamics: A Physical Model of Active Systemic Circulation [PDF]
Active fluid circulation and transport are key functions of living organisms, which drive efficient delivery of oxygen and nutrients to various physiological compartments. Because fluid circulation occurs in a network, the systemic flux and pressure are not simple outcomes of any given component. Rather, they are emergent properties of network elements

Neurologia medico-chirurgica, 1984 The dynamics of cerebrospinal fluid (CSF) circulation in 20 cases with hypertensive intracerebral hemorrhage was estimated with radioisotope cisternography (RIC) using In-111-DTPA. CT scan was performed simultaneously to observe the changes in the intracranial pathologies.

Cerebrospinal fluid dynamics and intracranial pressure elevation in neurological diseases
Fluids and Barriers of the CNS, 2019 The fine balance between the secretion, composition, volume and turnover of cerebrospinal fluid (CSF) is strictly regulated. However, during certain neurological diseases, this balance can be disrupted.

A unifying computational fluid dynamics investigation on the river-like to river-reversed secondary circulation in submarine channel bends [PDF]
, 2011 A numerical model of saline density currents across a triple-bend sinuous submerged channel enclosed by vertical sidewalls is developed. The unsteady, non-Boussinesq, turbulent form of the Reynolds Averaged Navier-Stokes equations is employed to study ...

Breaking Kelvin: Circulation conservation and vortex breakup in MHD at low Magnetic Prandtl Number [PDF]
arXiv, 2018 In this paper we examine the role of weak magnetic fields in breaking Kelvin's circulation theorem and in vortex breakup in two-dimensional magnetohydrodynamics for the physically important case of a low magnetic Prandtl number (low $Pm$) fluid. We consider three canonical inviscid solutions for the purely hydrodynamical problem, namely a Gaussian ...
