Abstract
The intermittent nature of energy dissipation in two-dimensional electron-m agnetohydrodynamic turbulence is investigated by means of high resolution d irect numerical simulations. It is found that, when the main contribution t o the energy is given by the magnetic field, dissipation is mostly concentr ated on one-dimensional filaments. As a consequence, the multifractal spect rum has a simple form which can be approximately described in terms of a bi fractal model. [S1063-651X(99)01803-6].
