| Zusammenfassung |
| As the dissipation mechanisms considered for the heating of the solar
corona would be sufficiently efficient only in the presence of small
scales, turbulence is thought to be a key player in the coronal heating
processes: it allows indeed to transfer energy from the large scales to
these small scales. While Direct numerical simulations which have been
performed to investigate the properties of magnetohydrodynamic turbulence
in the corona have provided interesting results, they are limited to small
Reynolds numbers. We present here a model of coronal loop turbulence
involving shell-models and Alfvén waves propagation, allowing the much
faster computation of spectra and turbulence statistics at higher Reynolds
numbers. We also present first results of the forward-modelling of
spectroscopic observables in the UV. |
