TO THE QUESTION OF CONTROL OF HYDRAULIC MODES OF THE HEAT NETWORK

International Journal of Advanced Studies, 2019
The mathematical modeling program Computational fluid dynamics is used. Research allows you to take into account all the factors affecting changes in hydrostatic pressure, to study the interaction process of the circulation pump, make-up unit and the ...

The motion of solid bodies in potential flow with circulation: a geometric outlook [PDF]

, 2008
The motion of a circular body in 2D potential flow is studied using symplectic reduction. The equations of motion are obtained starting front a kinetic-energy type system on a space of embeddings and reducing by the particle relabelling symmetry group ...

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.

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

Higher order dynamic mode decomposition beyond aerospace engineering

Results 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

Boundary Zonal Flow in Rotating Turbulent Rayleigh-Bénard Convection [PDF]

, 2019
For rapidly rotating turbulent Rayleigh–Bénard convection in a slender cylindrical cell, experiments and direct numerical simulations reveal a boundary zonal flow (BZF) that replaces the classical large-scale circulation.

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 ...

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.

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.

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 ...
