Sticky issues in turbulent transport. [PDF]

Ann Henri Poincare, 2022
We investigate the role of partial stickiness among particles or with a surface for turbulent transport. For the former case, we re-derive known results for the case of the compressible Kraichnan model by using a method based on bi-orthogonality for the expansion of the propagator in terms of left and right eigenvectors.

Anisotropy in Turbulent Flows and in Turbulent Transport [PDF]

Physics Reports, 2004
We discuss the problem of anisotropy and intermittency in statistical theory of high Reynolds-number turbulence (and turbulent transport). We present a detailed description of the new tools that allow effective data analysis and systematic theoretical ...

Multi-fidelity information fusion for turbulent transport modeling in magnetic fusion plasma [PDF]

Scientific Reports
Maintaining the high-temperature and pressure conditions required for sustained nuclear fusion is challenging due to the turbulent transport that naturally occurs in the plasma. Developing reliable models for turbulent transport is essential for progress

Averaging versus Chaos in Turbulent Transport? [PDF]

Communications in Mathematical Physics, 2004
In this paper we analyze the transport of passive tracers by deterministic stationary incompressible flows which can be decomposed over an infinite number of spatial scales without separation between them.

Charge Transport Scalings in Turbulent Electroconvection [PDF]

Physical Review E, 2005
We describe a local-power law scaling theory for the mean dimensionless electric current $Nu$ in turbulent electroconvection. The experimental system consists of a weakly conducting, submicron thick liquid crystal film supported in the annulus between ...

Multiscale Turbulent Transport [PDF]

, 2020
Turbulent transport is currently a prominent and ongoing investigation subject at the interface of methodologies from theory to numerical simulations and experiments, and it covers several spatiotemporal scales. Mathematical analysis, physical modelling, and engineering applications represent different facets of a classical, long-standing problem that ...

Non-Equilibrium Turbulent Transport in Convective Plumes Obtained from Closure Theory

Atmosphere, 2023
The non-equilibrium property of turbulence modifies the characteristics of turbulent transport. With the aid of response function formalism, such non-equilibrium effects in turbulent transport can be represented by the temporal variation of the turbulent
