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.

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 ...

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 ...

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.

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

Hamiltonian approach to hybrid plasma models [PDF]
, 2010 The Hamiltonian structures of several hybrid kinetic-fluid models are identified explicitly, upon considering collisionless Vlasov dynamics for the hot particles interacting with a bulk fluid.

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.

Planktonic communities and chaotic advection in dynamical models of Langmuir circulation [PDF]
, 1998 A deterministic mechanism for the production of plankton patches within a typical medium scale oceanic structure is proposed and investigated. By direct numerical simulation of a simple model of Langmuir circulation we quantify the effects of unsteady ...
