We have carried out 2D and 3D numerical simulations (Kaigorodov et al 2010, Fateeva et al. 2011, Sytov et al. 2011) of accretion processes in binary T Tauri stars (TTSs) DQ Tau, UZ Tau E, V4046 Sgr, GW Ori, RoXs 42C using a finite-difference Roe-Osher-Einfeld TVD scheme. The morphology of the flow pattern for UZ Tau E is shown in Fig. 1 (left panel). The flow structure includes accretion disks surrounding the components, bow-shocks in front of both the components, a shock wave (“bridge”) between the circumstellar accretion disks and a gap containing rarefied gas in the inner part of the protoplanetary disk.
