چکیده

A good understanding of the thermal hydraulic conditions resulting from steam-hydrogen releases in nuclear reactor containments is required for all aspects of accident management and for the design of mitigation measures. The GASFLOW II code has been developed at Forschungszentrum Karlsruhe (FZK) for analysis of such scenarios. It solves the three dimensional compressible transient Navier Stokes equations. This contribution will report on new validations of GASFLOW II with blind and open post-test simulations of experiments that simulate such conditions in the new ThAI containment test facility and in the Heissdampfreaktor (HDR) in Germany.

Modelling and Validation of Catalytic Hydrogen Recombination in the 3d Cfd Code Gasflow Ii

During hypothetical core melt accidents steam and hydrogen can be released into the air filled containment of pressurized water reactors (PWR). Without counter measures flammable mixtures may form and cause combustion loads that could threaten the integrity of the containment. German PWR’s are now equipped with passive catalytic recombiners so called PARs (passive autocatalytic recombiners). Th...

Assessment of the Gasflow Spray Model Based on the Calculations of the Tosqan

Within the framework of the EU (European Union) project SARNET (Severe Accident Research Network), spray experiments were performed in the TOSQAN facility in France. The experiments, Test 101 (thermal hydraulic part, without He release) and Test 113 (dynamic part, with He release), were selected for benchmark calculation with different CFD (Computational Fluid Dynamics) and LP (Lumped Parameter...

Computational fluid dynamics study and GA modeling approach of the bend angle effect on thermal-hydraulic characteristics in zigzag channels

In the study, the thermal-hydraulic performance of the zigzag channels with circular cross-section was analyzed by Computational Fluid Dynamics (CFD). The standard K-Ꜫ turbulent scalable wall functions were used for modeling. The wall temperature was assumed constant 353 K and water was used as the working fluid. The zigzag serpentine channels with bend angles of 5 - 45° were studied for turbul...
