Three Dimensional Simulation of Accretion Disks with Smoothed Particle Hydrodynamics
We performed three dimensional simulations of the mass transfer and the accretion disk formation in a close binary system. We used the Smoothed Particle Hydrodynamic interpolation method to solve the fluid dynamic equations. This method seems quite promising for its simplicity and efficient computing profile. Our results are compared to standard theoretical and numerical models. We find that the stream of cold gas falling on the compact star forms the disk in the conventional way, a strong shock develops and penetrates deep into the disk. However, since our numerical viscosity is still high we cannot establish if spiral shocks are forming.
