Scientific paper

The numerical method developed for investigations of accretion in close binaries described in Paper I of this series (Hensler, t982b) is applied to systems of different parameters. 2D hydrodynamical calculations have been carried out to obtain steady accretion disks. We present surface density and radiation flux distributions as results of disk models for binary systems of the following parameters: 1. q=3., τ=3.d, d=13.89Rsun, Mdot=10-8 Msun yr-1, 2. and 3. q=2., τ=0.2d, d=1.65Rsun, Mdot = 10-9 Msun yr-1 chosen to represent a Cataclysmic Variable, first, at the stationary state resembling the outburst phase and, secondly, during quiescence. The results are discussed by comparison with theoretical investigations and interpretations of observations.
