Simulations of Two-Phase Flow in Fluent
Original language description
Paper presents the recent efforts on simulating two-phase flow of Pb-Bi and steam in 2D using the CFD code Fluent. The study was performed in support of the Pb-Bi cooled direct contact steam generation fast reactor in which water is injected directly above the core; the produced steam is separated at the top and is send to the turbine. The simulation used volume of fluid explicit model and set the other important simulation parameters as follows: pressure velocity relation PISO, discretization scheme body force weighted for pressure and the second order upwind for momentum. For void fraction the donor-acceptor model appears to perform the best, CISCAM gives similar results, but finer mesh is required. The mass flow boundary condition was used at the inlet and the mass flows were set 0 kg/s for Pb-Bi and 0.07 kg/s for steam. At the outlet the pressure outlet boundary condition was used.
