The complex flow in the junction includes separation, impingement and secondary flow. The mathematical model is based on unsteady Reynolds-averaged Navier-Stokes equations with an explicit algebraic Reynolds stress turbulence model. The solution method uses the dual time artificial compressibility scheme with the upwind finite volume discretization. Some methods of ensuring prescribed flow-rate distribution are tested and discussed. Numerical results are compared with PIV measurement.
