| 520 | _ | _ | |a Hydrogen mixing and distribution in a nuclear power plant containment during a postulated severeaccident is a phenomenon with high safety relevance for current and advanced LWR. The OECD/NEASETHproject was carried out to generate the experimental data on basic containment phenomena with therequired instrumentation to assess CFD and LP codes.In this paper, we analyzed the PANDA Test 16 of the OECD/NEA-SETH project by usingcontainmentFOAM which is a tailored open-source CFD code package for containment analysisdeveloped at Forschungszentrum Jülich (Germany) based on OpenFOAM® v9. SETH Test 16 addressedsteam-air mixture transport driven by jets and plumes in the multi-compartment PANDA facility (Vessel 1,Vessel 2 and Interconnecting pipe, IP) at Paul Scherrer Institut (Switzerland). Steam is injected with 0.040kg/s and 140 ºC in Vessel 1 which is initially filled with dry air at 108 ºC and created a wall-plume.Steam-air mixtures are vented out from Vessel 2. The system pressure is constant at 1.3 bar for the wholetest duration (4000 s).Sensitive studies have been performed considering different models for the buoyancy turbulenceproduction and dissipation terms in k-w SST model. The distribution of steam molar fraction andtemperature are well expected above the injection tube in Vessel 1 and over the height of Vessel 2. While,below the injection tube in Vessel 1 some discrepancies between the simulations and experimental resultswere observed.KEYWORDSPANDA, Multi-compartment, Buoyancy turbulence model, CFD, containmentFOAM |
