A NEW NUMERICAL SCHEME FOR RESISTIVE RELATIVISTIC MAGNETOHYDRODYNAMICS USING METHOD OF CHARACTERISTICS

摘要: We present a new numerical method of special relativistic resistive magnetohydrodynamics with scalar resistivity that can treat range phenomena, from nonrelativistic to (shock, contact discontinuity, and Alfv\'en wave). The scheme calculates the flux fluid by using an approximate Riemann solver, electromagnetic field characteristics. Since this uses appropriate characteristic velocities, it is capable accurately solving problems cannot be approximated as ideal whose velocity much lower than light velocity. results show our solve above well nearly MHD problems. Our particularly suited systems initially weak magnetic field, mixed phenomena non-relativistic velocity; for example, MRI in accretion disk, super Alfv\'enic turbulence.
