Demonstration for Novel Self-Organization Theory by Three-DimensionalMagnetohydrodynamic Simulation

摘要

It is demonstrated by three-dimensional simulations for resistivemagnetohydrodynamic (MHD) plasmas with both 'spatially nonuniform resistivity eta' and 'uniform eta' that the attractor of the dissipative structure in the resistive MHD plasmas is given by del x (eta)j) = (alpha/2)B which is derived from a self-organization theory based on the minimum dissipation rate profile. It is shown by the simulations that the attractor is reduced to del x B = (lambda)B in the special case with the 'uniform eta' and no pressure gradient.
