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…
