Single-mode nonlinear Langevin emulation of magnetohydrodynamic turbulence
arXiv:1805.04630 · doi:10.1103/PhysRevE.97.053211
Abstract
Based on the Langevin equation of Brownian motion, we present a simple model that emulates a typical mode in incompressible magnetohydrodynamic turbulence, providing a demonstration of several key properties. The model equation is consistent with von Kármán decay law and Kolmogorov's symmetries. We primarily focus on the behavior of inertial range modes although we also attempt to include some properties of the large scale modes. Dissipation scales are not considered. Results from the model are compared with results from published Direct Numerical Simulations.
