A Symplectic Theory of Turbulence Closure: Hidden Reservoir Dynamics, Endogenous Stochastic Transport, and Kraichnan Dual Cascades
Mickaël D. Chekroun, James C. McWilliams
The equations of fluid motion are known; retaining their physics after removing most degrees of freedom remains a fundamental problem. Closure must preserve the geometry of the dyn…
Non-Markovian Reduced Models to Unravel Transitions in Non-equilibrium Systems
Mickaël D. Chekroun, Honghu Liu, James C. McWilliams
This work proposes a general framework for capturing noise-driven transitions in spatially extended non-equilibrium systems and explains the emergence of coherent patterns beyond t…
Large-Scale Magnetic-Field Generation by Randomly Forced Shearing Waves
T. Heinemann, J. C. McWilliams, A. A. Schekochihin
A rigorous theory for the generation of a large-scale magnetic field by random non-helically forced motions of a conducting fluid combined with a linear shear is presented in the a…
Numerical experiments on dynamo action in sheared and rotating turbulence
T. A. Yousef, T. Heinemann, F. Rincon +5
Numerical simulations of forced turbulence in elongated shearing boxes are carried out to demonstrate that a nonhelical turbulence in conjunction with a linear shear can give rise…
Fluctuation dynamo and turbulent induction at low magnetic Prandtl numbers
A. A. Schekochihin, A. B. Iskakov, S. C. Cowley +3
This paper is a detailed report on a programme of simulations used to settle a long-standing issue in the dynamo theory and demonstrate that the fluctuation dynamo exists in the li…
Numerical demonstration of fluctuation dynamo at low magnetic Prandtl numbers
A. B. Iskakov, A. A. Schekochihin, S. C. Cowley +2
Direct numerical simulations of incompressible nonhelical randomly forced MHD turbulence are used to demonstrate for the first time that the fluctuation dynamo exists in the limit…
