Abstract

Solar flares occur when magnetic energy is quickly converted into heat and kinetic energy by magnetic reconnection in a current sheet (CS). We briefly discuss previous works on the CS thickness estimated from observations by the UVCS and the LASCO experiments on SOHO. Based on these results, we perform 2D MHD simulations of the development of instabilities and turbulence in a long CS and study various properties of the energy conversion in the reconnection region. Our results display a very good power law distribution for the energy versus the scale of small structures inside CS, and suggest that the reconnection process is turbulent.
