Shear Flows and Turbulence in Nature

Computing in Science & Engineering, 2007
Shear flows and turbulence have a major impact on the transport of quantities, from heat to material to pollutants. This article explores transport and its sensitivity to novel interactions between shear flow and turbulence.

One-dimensional turbulence: model formulation and application to homogeneous turbulence, shear flows, and buoyant stratified flows

Journal of Fluid Mechanics, 1999
A stochastic model, implemented as a Monte Carlo simulation, is used to compute statistical properties of velocity and scalar fields in stationary and decaying homogeneous turbulence, shear flow, and various buoyant stratified flows. Turbulent advection is represented by a random sequence of maps applied to a one-dimensional computational domain ...

E×B shear flows and electromagnetic gyrofluid turbulence

Physics of Plasmas, 2000
Low frequency tokamak edge turbulence is modelled numerically using gyrofluid equations for electrons and ions on an equal footing. The electrons are electromagnetic, and arbitrarily strong finite gyroradius effects are included for the ions. Computations are in a globally consistent truncation of flux surface geometry arising from ideal tokamak ...

Sheared flows and turbulence in fusion plasmas

Plasma Physics and Controlled Fusion, 2007
The universality of the observed characteristics of sheared flows points to a general ingredient to explain the damping/driving mechanisms responsible for the development of these flows in the plasma boundary region of fusion devices. Experiments in the TJ-II stellarator showing that the generation of spontaneous sheared flows at the plasma edge ...

Turbulence and Sheared Flow

Science, 1998
Achieving nuclear fusion in magnetically confined plasma has been frustrated by turbulence that rips the plasma apart. In his Perspective, Burrell discusses recent efforts to understand and control microturbulence-small-scale plasma eddies that dominate the loss of energy from tokamak plasmas. Such efforts include those reported by [ Lin et al. ][1] in
