Outline of Final Research Achievements

The goal of this research is to develop our understanding of mixing process by turbulent plasmas in wave numeber, real, and velocity space. In particular, we focus on the role of secondary flows and their feedback on the underlying turbulence, and impact on non-local transport processes. When developing models for mixing with the degree of freedom in velocity space, impact on real space phenomena is emphasized. Numerical and physical experiments are proposed to test predictions from the theory of phase space turbulence.
