Investigations of the Role of Nonlinear Couplings in Structure Formation and Transport Regulation: Experiment, Simulation and Theory
Abstract
Flow shear layer generation and amplification by turbulence are now recognized as crucial in regulating both core transport and barrier formation (i.e. L-H transition). The theoretical description of the dynamics of these phenomena is based upon nonlinear coupling processes, such as modulational and parametric instabilities, and inverse cascades. In this paper, we report on integrated experimental, computational, and theoretical studies of sheared zonal flows and radially extended cells. The aim is to assess the results of theory-experiment and theory-simulation comparisons.
