Depletion of nonlinearity and self-organization in fluid and plasma turbulence
Wouter BOS
Ecole Centrale Lyon
In this talk we will discuss a possibly universal feature of turbulent systems, namely, the fact that turbulence tends to reduce the strength of the nonlinearity in its governing equations. This feature is shown to be observed in a range of different systems in fluid dynamics and plasma physics. It is discussed how this phenomenon is connected to the self-organization of the flow field into coherent structures.
