Nusselt number scaling in tokamak plasma turbulence [PDF]
Physics of Plasmas, 2005 Anomalous heat transport caused by ion temperature gradient (ITG) driven turbulence in tokamak plasmas is evaluated from numerical simulations of the two-dimensional (2D) partial-differential equations of the ITG model and of a reduced 1D version derived from a quasilinear approximation.
