Resistive fluid turbulence and energy confinement

The invariance properties of the underlying equations under scale transformations provide information about plasma transport. By applying this argument to specific models, in which the magnetic configuration and the physical mechanism of transport are identified, this information can be sufficient to completely determine the transport coefficients in a turbulent plasma. In this way the electron energy transport due to resistive fluid turbulence is examined in tokamak and reversed field pinch configuration. The resulting confinement times have interesting implications for the performance of the two systems.
