Three-dimensional hydrodynamic simulation of an accretion flow in a close binary system

摘要: Three-dimensional hydrodynamic simulations of Roche-lobe overflow are performed by solving the Euler equations. The gas is assumed to be inviscid and adiabatic except in case shocks. Gas filling critical Roche lobe a mass-losing component flows through L1 point towards compact object form an accretion disc. It found that disc not axisymmetric but characterized pair spiral shocks, as was two-dimensional calculations
