Query: A Numerical Model for Accretion in Intermediate Polars with Dipolar
  Magnetic Fields   A three-dimensional numerical model for an accretion process investigation in
the magnetosphere of a white dwarf in magnetic cataclysmic variables is
developed. The model assumes that the white dwarf has a dipole magnetic field
with its symmetry axis inclined to the rotation axis. The model is based on the
equations of modified MHD, that describe the mean flow parameters in the wave
MHD turbulence. Diffusion of the magnetic field and radiative heating and
cooling are taken into account. The suitability of the model is confirmed by
modeling the accretion in a typical intermediate polar. The computations show
that a magnetosphere forms around the accretor, with the accretion occurring
via columns. The accretion columns have a curtain-like shape, and arc-shaped
zones of energy release form on the surface of the white dwarf in the magnetic
poles area as a result of the matter infall.
