dc.descriptionThe results of three-dimensional numerical simulations of mass transfer in semidetached binaries after mass transfer termination is presented and the structure of residual accretion disk was investigated. It was shown that after the mass transfer termination the quasi-elliptic accretion disk becomes circular. It was also shown that the cessation of mass transfer results in changing of the structure of the accretion disk: the second arm of spiral shock is appeared as well as a new dense formation (blob), the latter moving through the disk with variable velocity. The blob doesn't smear out under the action of dissipation but is sustained by interaction with arms of spiral shock for practically all the lifetime of the disk. We also analyze the dependence of disk's lifetime on the value of viscosity. For the value of parameter $α$ that is typical for observing accretion disk ($α\sim0.01$) the lifetime of residual disk is found to be equal to 50 orbital periods.
