Abstract

The transport if tracer particles in plasma turbulence was studied using a three dimensional transport model. The model was formulated using fractional derivative operators which helped to study the non-local effects in space and time. The moments of tracer displacement was found to be exhibiting superdiffusive scaling. The transport process with different degrees of left-right asymmetry was modeled by appropriate election of weighing factors in fusion plasmas.
