Numerical simulations of flow through channels with T-junction
Original language description
The paper deals with numerical solution o f laminar and turbulent flows of Newtonian and non-Newtonian fluids in branched channels with two outlets. Mathematical model of the flow is based on the Reynolds averaged Navier-Stokes equations for the incompressible fluid. In the turbulent case, the closure of the system of equations is achieved by the explicit algebraic Reynolds stress (EARSM) turbulence model. Generalized non-Newtonian fluids are described by the power-law model. The governing equations aresolved by cell-centered finite volume schemes with the artificial compressibility method; dual time scheme is applied for unsteady simulations. Channels considered in presented calculations are of constant square or circular corss-sections. Numerical results for laminar flow of non-Newtonian fluid are presented. Further, turbulent flow through channesl with perpendicular branch is simulated. Possible methods for setting the flow rate are discused and numerical results presented for two
