Workshop, August 10-14

Oral

Turbulence modeling provides a powerful tool for investigating realistic turbulence with large-scale inhomogeneities. An attempt to study fast reconnection with the aid of self-consistent turbulence model is introduced. Turbulence related to magnetic reconnection is not homogeneous-isotropic at all. Its statistical properties depend on the large-scale configurations of the...

378. Turbulent reconnection

Workshop, August 10-14

Invited

Turbulence is a natural state of high Reynolds flows and is ubiquitous in astrophysical systems. In most cases turbulence is externally driven, but one also expects the outflows induced by reconnection to get turbulent. High resolution numerical resolution reconnection simulations in 3D also show the transition to the turbulent state. Therefore it is essential to understand how...

361. In situ study of reconnection and associated electron heating in thin current sheets

Alexandros Chasapis (Laboratoire des Physiques des Plasmas)

Workshop, August 10-14

Oral

We present an in situ study of thin current sheets and associated electron heating in turbulent space plasma. We use Cluster observations made in the turbulent plasma downstream of the Earth's quasi-parallel shock and we analyze the properties of ion-scale current sheets. Intermittent structures were identified using the Partial Variance of Increments method. We studied the...
