摘要：

The work deals with the numerical simulations of a 3D incompressible viscous turbulent flow in the branched channels with circular cross section. The mathematical model is based on the unsteady Reynolds averaged Navier-Stokes (URANS) equations with the explicit algebraic Reynolds stress (EARSM) turbulence model. The resulting set of partial differential equations is then solved by artificial compressibility method in dual time in the finite volume formulation. The flow through the round branched channel with branch perpendicular to the main channel (T-junction) is considered. Diameter of the main channel is 50mm and diameter of the branch is 32mm. Different combinations of inlets and outlets and different flow rates are studied.
