Abstract

The work deals with numerical 3D simulations of incompressible turbulent flow in channel junction with one inlet and two outlets. The complex flow in the junction includes separation, impingement and secondary flow. The mathematical model is based on unsteady Reynolds averaged Navier-Stokes equations (URANS) with an explicit algebraic Reynolds stress turbulence model (EARSM). The solution method uses dual time artificial compressibility scheme with upwind finite volume discretization. Some methods of ensuring prescribed flow-rate distribution are discussed and tested. The results are compared with PIV measurement.
