EVOLUTION IN LATER-TIME HANE PLASMAS

STRIATIONS WITHIN NUCLEAR PLUMES CAN BE EXPECTED TO HAVE VERY NEGATIVEEFFECTS UPON COMMUNICATIONS, BECAUSE OF THEIR ENORMOUS SIZE, PERSISTENCE, AND RELATIVELY HIGH DENSITY. WE PROPOSE THE DEVELOPMENT OF A THREE-DIMENSIONAL NUMERICAL SIMULATION CODE TO STUDY THE EFFECTS OF FINITE PARALLEL RESISTIVITY, ELECTROMAGNETIC FIELDS, ION-NEUTRAL COLLISIONS, ION INERTIA, AND ION VISCOSITY UPON THE EVOLUTION OF STRIATIONS. IN PHASE I, THE FEASIBILITY AND METHODOLOGY OF THE CODE DEVELOPMENT WOULD BE DETERMINED. IF SUCCESSFUL, THE THREE-DIMENSIONALSIMULATION COULD PERMIT PRECISE DETERMINATION OF THE PHYSICS CONTROLLING THE MICROSTRUCTURE PROBLEM, ADDRESSING QUESTIONS, WHICH PRESENTLYAVAILABLE CODES CANNOT ANSWER, RELATING TO THE TENDENCY OF STRIATIONS TO DEVELOP WITH PREFERENTIAL TRANSVERSE SCALE SIZES AND TO THE LONGTERM PRESISTENCE OF STRIATION AS SEEMINGLY FIELD-ALIGNED ENTITIES. THIS COULD CRUCIALLY ASSIST IN THE DEVELOPMENT AND EVENTUAL IMPLEMENTATION OF MORE REALISTIC MICROSTRUCTURE ALGORITHMS IN NUCLEAREFFECTS SIMULATION CODES LIKE SCENARIO.
