CALCULATION OF A SPACE MODEL OF THE INTERACTION OF SUNNY WIND WITH THE MAGNETIC FIELD OF THE EARTH

Space equations of ideal magnetic hydrodynamics, numerical methods for their solution in pre-sound and supersound fields of a flow are investigated in the paper aiming at the development of effective numerical methods for the calculation of magnetohydrodynamic space steady-state flows for the process modelling of the flow of the Earth's magnetopause by sunny wind. As a result the methodology of the Cauchy problem calculation for model linear and non-linear equations of transfer with discontinuous initial data by the method of pseudocharacteristics has been developed. A system of MHD equations for the analysis of the Cauchy problem solvability on characteristic surfaces has been investigated. The numerical method of pseudocharacteristics for the calculation of a supersound space MHD-flow in an external problem of the flow with a removed shock wave has been developed. The effective method for the calculation of a space model of the interaction of sunny wind with the magnetic field of the Earch has been created. Calculations of the interaction of sunny plasma with magnetopause have been heldAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
