Fluid models for two‐dimensional, electron energy transport are examined. It is shown that enhanced lateral transport due to particle drifts in self‐generated magnetic fields occurs when certain transport terms are flux‐limited by artificially enhancing collisions. With flux limiting, fluid models reproduce the essential features of numerical simulations of transport in CO 2 laser target experiments.
