Velocity circulation intermittency in finite-temperature turbulent superfluid helium [PDF]
arXiv, 2022 We study intermittency of circulation moments in turbulent superfluid helium by using experimental grid turbulence and numerical simulations of the Hall-Vinen-Bekarevich-Khalatnikov model. More precisely, we compute the velocity circulation $\Gamma_r$ in loops of size $r$ laying in the inertial range.

Implications of Kunita–Itô–Wentzell Formula for k-Forms in Stochastic Fluid Dynamics [PDF]
Journal of nonlinear science, 2019 We extend the Itô–Wentzell formula for the evolution of a time-dependent stochastic field along a semimartingale to k-form-valued stochastic processes. The result is the Kunita–Itô–Wentzell (KIW) formula for k-forms.

Material derivatives of higher dimension in geophysical fluid dynamics
Meteorologische 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.

Conservation of the circulation for the Euler and Euler-Leray equations [PDF]
Phys. Rev. Fluids 4, 084401 (2019), 2019 It is well-known that the circulation of the velocity field of a fluid along a closed material curve is conserved for any solution of the Euler equation. We offer a slightly more explicit proof of that fact than that generally found in the literature.

Vortex Gas Modeling of Turbulent Circulation Statistics [PDF]
Phys. Rev. E 102, 041102 (2020), 2020 Statistical properties of circulation encode relevant information about the multi-scale structure of turbulent cascades. Recent massive computational efforts have posed challenging theoretical issues, as the dependence of circulation moments upon Reynolds numbers and length scales, and the specific shape of the heavy-tailed circulation probability ...

Cerebrospinal fluid dynamics with its surgical implications
Romanian Neurosurgery, 2020 Cerebrospinal fluid (CSF) is largely (70-80%) produced by the choroids plexus of the ventricles and is considered as the plasma ultrafiltrate. While CSF formation, circulation, and composition appear to be physiological and physical, its absorption ...

Computational fluid dynamic simulations of a cavopulmonary assist device for failing Fontan circulation [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 2019 Adult patients who have undergone the Fontan procedure are highly vulnerable to gradual, progressive circulatory failure, and options to reverse this situation are few. A cavopulmonary assist device could decongest the venous and lymphatic systems, overcome elevated pulmonary vascular resistance, increase cardiac output, and support some of these ...

The power of microRNA regulation—insights into immunity and metabolism
FEBS Letters, EarlyView.MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...
