Large scale forcing of a turbulent plasma dynamo
Résumé
This investigation focuses on the forcing of a large scale velocity field in a plasma. The ultimate goal of the project is to develop efficient stirring mechanisms in order to generate a large-scale driven turbulent flow in a plasma vessel and to generate, and better understand, a large scale dynamo. Numerical simulations are carried out using recently developed numerical methods for plasma flows. It is shown how the vessel can be stirred by locally imposing an electric field, and what the resulting three dimensional flow-field looks like.
