A Test for the Viability of Fluid Codes in the Collisionless Regime.
Abstract
A collisionless unmagnetized plasma can multistream. Therefore, it is not clear to what extent fluid codes can be used to describe its motion. A simple test is presented here which shows when a collisionless plasma multistreams. If a temperature equation formulation of the energy equation is used, it is shown that the system continuously and unavoidably loses energy when multistreaming occurs.
