The Use of Vibrating Structures in the Study of Quantum Turbulence

Vibrating structures such as disc, spheres, grides and wires have been widely used in research on quantum fluids. Superflow is subject to severe quantum restrictions. Quantum turbulence differs from that in classical fluids. The tra...

Poloidal structure of the turbulence and the turbulent flux during edge plasma biasing in the Castor tokamak.

The poloidal structure of the turbulence and the turbulent particle flux in the scrape-off layer (SOL) of the CASTOR tokamak are analysed by means of a poloidal ring of 124 probes distributed uniformly along the whole poloi...

Ordes, disorder, chaos and turbulence

The artcle deals with contemporary concept of the turbulence. This is considered as natural behaviour of a non-linear dynamical system, when self-ordering - epicureans. In the end, the turbulent behaviour of a dynamical system based...
