Abstract
Turbulent transport with trapped electrons is simulated with a two-dimensional (2-D) representation. The trapped particles are lumped into hot and cold fluids to treat temperature gradient effects. The ion temperature gradient and dissipative trapped electron modes are simultaneously present. The hot and cold lumped fluid model was found to represent the true kinetic model linearly. The numerically simulated transport compares very well with detailed quasilinear expressions. A plasma particle pinch is found only at extremely low collisionalities and a heat conduction pinch is found at moderate collisionalities, although there is no energy flow pinch seen.
