We have studied magnetic reconnection and shear flow instabilities using a new-compact algorithm recently designed, which combines high-order techniques both in space and time, to follow magnetic reconnection developing in current-sheets, together with shock-capturing capabilities, able to handle field discontinuities often developing in a compressible plasma. In particular we have followed the three-dimensional non-linear evolution of the tearing instability and its transition towards a turbulent state, and we have also investigated the acceleration properties of a sheared flow where a current sheet is embedded, a model for the acceleration of the slow solar wind above helmet streamers.

Abstract
We have studied magnetic reconnection and shear flow instabilities using a new-compact algorithm recently designed, which combines high-order techniques both in space and time, to follow magnetic reconnection developing in current-sheets, together with shock-capturing capabilities, able to handle field discontinuities often developing in a compressible plasma. In particular we have followed the three-dimensional non-linear evolution of the tearing instability and its transition towards a turbulent state, and we have also investigated the acceleration properties of a sheared flow where a current sheet is embedded, a model for the acceleration of the slow solar wind above helmet streamers.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
