Mesoscopic transport in KSTAR plasmas: avalanches and the staircase
Minjun J. Choi, Jae-Min Kwon, Lei Qi +18
The self-organization is one of the most interesting phenomena in the non-equilibrium complex system, generating ordered structures of different sizes and durations. In tokamak pla…
Stochastic fluctuation and transport of tokamak edge plasmas with the resonant magnetic perturbation field
Minjun J. Choi, Jae-Min Kwon, Juhyung Kim +17
We present that a statistical method known as the Complexity-Entropy analysis is useful to characterize a state of plasma turbulence and flux in the resonant magnetic perturbation…
Evolution of magnetic Kubo number of stochastic magnetic fields during the edge pedestal collapse simulation
Jaewook Kim, Wonjun Lee, Hogun Jhang +3
Using a statistical correlation analysis, we compute evolution of the magnetic Kubo number during an edge pedestal collapse in nonlinear reduced magnetohydrodynamic simulations. Th…
Experimental evidence of the non-diffusive avalanche-like electron heat transport events and their dynamical interaction with the shear flow structure
Minjun J. Choi, Hogun Jhang, J. -M. Kwon +12
We present experimental observations suggesting that the non-diffusive avalanche-like events are a prevalent and universal process of the electron turbulent heat transport in tokam…
A quasi-linear analysis of the impurity effect on turbulent momentum transport and residual stress
S. H. Ko, Hogun Jhang, R. Singh
We study the impact of impurities on turbulence driven intrinsic rotation (via residual stress) in the context of the quasi-linear theory. A two-fluid formulation for main and impu…
A mechanism for magnetic field stochastization and energy release during an edge pedestal collapse
Tongnyeol Rhee, Sung Sik Kim, Hogun Jhang +2
On the basis of three-dimensional nonlinear magnetohydrodynamic simulations, we propose a new dynamical process leading to the stochastization of magnetic fields during an edge ped…
