Aspects of Turbulent Transport
Contributions to Plasma Physics, 2004AbstractTurbulence is an ubiquitous phenomenon in plasmas, which usually have large amounts of free energy available to drive turbulent velocity fluctuations. A universal property of turbulence is its abilities to mix and to transport quantities. We discuss the relationship between passive particle transport due to turbulence and the turbulent plasma ...

Transport Phenomena in Turbulent Flows
2015In this chapter we intend to provide a brief introduction to the study of transport phenomena in the presence of turbulent flows. This is a very large and quite specialized topic, and here we will confine our treatment to some basic features, above all in the context of pipe flow, referring the interested readers to more specialized texts (See, for ...

Turbulent MHD transport coefficients
Plasma Physics and Controlled Fusion, 1999Previous calculations of turbulent magnetohydrodynamic (MHD) eddy viscosity and anomalous resistivity are reviewed. Emphasis is laid on a new approach to fully developed turbulence proposed by Canuto and Dubovikov, containing both systematic and heuristic elements for the ultraviolet (UV) and infrared (IR) parts of the nonlinear interactions in ...

Transport Phenomena in Rotating Turbulence
2017The role of rotation on turbulence and some of its transport properties will be reviewed with emphasis on two specific cases: statistically steady or decaying rotating turbulence and rotating thermally driven turbulence. For this purpose we briefly address a few basic concepts relevant for understanding processes in rotating (turbulent) flows such as ...

Turbulent transports over tundra
Journal of Geophysical Research: Atmospheres, 1992Measurements of the surface fluxes of heat, momentum, and water vapor using the eddy correlation technique were made from instruments on a 12‐m tower at a remote site in the western Alaskan tundra between July 13 and August 12, 1988. Except for advection, all of the terms in the heat and moisture balances were measured directly. Diurnal averages of the

Transport Equations in Turbulence
The Physics of Fluids, 1970Turbulence transport equations, describing the dynamics of transient flow of an incompressible fluid in arbitrary geometry, have been derived in such a manner as to incorporate the principles of invariance (tensor and Galilean) and universality. The equations are described in detail and their applicability is demonstrated by comparison of solutions ...

Turbulent Transport in Tokamak
2015Drift waves in Chap. 5 is most likely candidates of turbulent transport in tokamak and flow shear is key to reduction of turbulent transport. The turbulence itself can produce flow and flow shear through zonal flow and mean flow, which plays essential role for realizing fusion burn in ITER.

A review is presented of turbulent transport phenomena in flames. Both large-scale turbulent transport and small-scale mixing processes are considered and various mechanisms of interaction between combustion and turbulent flow are identified. Flame-surface density descriptions of turbulent combustion at high Damköhler numbers are discussed in detail ...

The flow of wind over crop canopies causes a transfer of momentum from the air to the canopy that generates turbulence which enhances the exchange of matter and energy between the atmosphere and crops. Turbulence increases with wind velocity and aerodynamic roughness which is proportional to crop height.
