About the new two-stage linear solver preconditioner for numerical solution of viscous multiphase flow in porous media

Abstract

For solution of the linear system arising at numerical modelling of multiphase filtering of viscous compressed mixture in the porous environment, it is considered предобуславливатель CPR. Modification предобуславливателя CPR on the basis of decomposition of settlement area on steady and unstable is offered at the fixed time step and implicit sampling. Efficiency matching предобуславливателей CPR and ACPR on real two and three-phase tasks is spent.
