Fluid mixing and flow distribution in a primary circuit of a nuclear pressurized water reactor - Validation of CFD codes
Original language description
The EU project FLOMIX-R was aimed at describing the mixing phenomena relevant for both safety analysis, particularly in steam line break and boron dilution scenarios, and mixing phenomena of interest for economical operation and the structural integrity.This report focuses on the computational fluid dynamics (CFD) code validation. CFD calculations have been accomplished for selected experiments with two different CFD codes (CFX, FLUENT). The matrix of benchmark cases contains slug mixing tests simulating the start-up of the first main circulation pump which have been performed with three 1:5 scaled facilities: the Rossendorf coolant mixing model ROCOM, the Vattenfall test facility and a metal mock-up of a VVER-1000 type reactor. The results of the CFDcalculations are mostly in-between the uncertainty bands of the experiments. It can be concluded about the suitability of applying CFD methods in engineering applications for turbulent mixing in nuclear reactors.
