Title:

Two-dimensional Electron Magnetohydrodynamic Turbulence

Date of publication:

Nov. 1995

Key words:

electron magnetohydrodynamics, turbulence, collisionless reconnection

Abstract:

A novel type of turbulence, which arises in 2D electron magnetohydrodynamics, is studies by numerical simulation. Energy dissipation rates are found to be independent of the dissipation coefficients. The energy spectrum E_k follows the basic Kolmogorov-type predictions, k^-5/3 for kd_e > 1 and k^-7/3 for kd_e < 1 (d_e=electron inertial length) and is hence independent of the linear wave properties. Results are compared with other 2D turbulent systems.
