Results for a turbulent system with unbounded viscosities: weak formulations, existence of solutions, boundedness, smoothness' [PDF]
, 2007 We consider a circulation system arising in turbulence modelling in fluid dynamics with unbounded eddy viscosities. Various notions of weak solutions are considered and compared. We establish existence and regularity results.

Veins and Lymphatics, 2018 Ménière’s disease (MD) is a pathology of the inner ear, the symptoms of which include tinnitus, vertigo attacks, fluctuating hearing loss, and nausea. Neither cause nor cure are currently known, though animal experiments suggest that disruption of the ...

Fluid dynamic similarity of circulating fluidized beds
Powder Technology, 1992 Abstract The effects of scale-up on the fluid dynamics of circulating fluidized beds (CFB) are investigated using a single cold laboratory facility with the ability to recycle fluidization gas mixtures of adjustable density and viscosity. By matching five dimensionless parameters, experiments employing plastic, glass and steel powders achieve fluid ...

Flow networks: A characterization of geophysical fluid transport [PDF]
, 2015 We represent transport between different regions of a fluid domain by flow networks, constructed from the discrete representation of the Perron-Frobenius or transfer operator associated to the fluid advection dynamics.

Multisymplectic formulation of fluid dynamics using the inverse map [PDF]
, 2007 We construct multisymplectic formulations of fluid dynamics using the inverse of the Lagrangian path map. This inverse map, the ‘back-to-labels’ map, gives the initial Lagrangian label of the fluid particle that currently occupies each Eulerian position.

Single-layer Axisymmetric Model for a Hadley Circulation with Parameterized Eddy Momentum Forcing
Journal of Advances in Modeling Earth Systems, 2009 An axisymmetric single-layer model is used to study interactions of the Hadley circulation with extratropical eddies. Eddy momentum fluxes are parameterized using a simple closure motivated by calculations with an idealized dry general circulation model (

Effects of Salinity Variability on Recent El Niño Events
Atmosphere, 2019 Ocean salinity variability provides a new way to study the evolution of the the El Niño-Southern Oscillation (ENSO). Comparisons between the salinity variation and related processes responsible for sea surface temperature anomaly (SSTA) were ...

Fluid circulation driven by collectively organized metachronal waves in swimming T. aceiti nematodes [PDF]
, 2022 Recent experiments have shown that the nematode {\it T. aceti} can assemble into collectively undulating groups at the edge of fluid drops. This coordinated state consists of metachronal waves and drives fluid circulation inside the drop. We find that the circulation velocity is about 2 mm/s and nearly half the speed of the metachronal wave. We develop

Fluid Dynamic Relationships Involved in Circulation Cleaning
Journal of Dairy Science, 1968 Abstract Removal of milk deposits on metal pipes using only fluid flow, without benefit of detergent materials, was studied. Soil removal rate was linear at flow rates between 4,000 and 30,000 kg/hour, representing Reynolds Numbers of from 85,000 to 600,000, demonstrating that cleaning effectiveness steadily improved as the pumping rate increased.

Si3N4 and Si3N4/SiC composite rings for dynamic sealing of circulating fluids [PDF]
Wear, 2003 Abstract Silicon nitride (Si3N4) and silicon nitride/silicon carbide (Si3N4/30 wt.% SiC) seal rings were tested as self-mated pairs and dissimilar sealing systems against grey cast iron. The tribological experiments were conducted in a ring-on-ring tribometer at V≈4 m s−1 of linear speed, in the range of 0.3–1 kN of applied load, under a pressure of ...
