| Research Abstract |
In burning plasmas in magnetic confinement fusion device, the pressure-gradient-driven turbulence is affected by the ignition, so that long wavelength fluctuations are established. In this research project, a theoretical basis for turbulent transport was established, in which nonlinear interactions between microscopic and mesoscopic/macroscopic fluctuations are correctly introduced. For instance, turbulent viscosity was formulated, by renormalizing higher order nonlinear effects of zonal flows. In addition, the seesaw mechanism of turbulent transport was proposed. Theoretical results form the basis for understanding and controlling fusion burning plasmas.
