Summary: This paper is interested in the numerical simulation of steady flows of laminar incompressible viscous and viscoelastic fluids through the channel with T-junction. The flow is described by the system of generalized incompressible Navier-Stokes equations. For the different choice of fluids model the different model of the stress tensor is used, Newtonian and Oldroyd-B models. Numerical tests are performed on three dimensional geometry, a branched channel with one entrance and two outlet parts. Numerical solution of the described models is based on cell-centered finite volume method using explicit Runge-Kutta time integration.
