GASFLOW-MPI is a widely validated parallel CDF code and has been applied to containment thermal hydraulics safety analysis for different types of reactors. The essential issue for PCCS is the heat removal capability. Research shows that film evaporation contributes most to the heat removal capability...
PETSC-based parallel semi-implicit CFD code GASFLOW-MPI in application of hydrogen safety analysis in containment of nuclear power plant. In: Joint International Conference on Mathematics and Computation (M&C), Supercomputing in Nuclear Applications (SNA) and the Monte Carlo (MC) Method, Nashville,...
Specifically, the Korean PAR was modeled by GASFLOW-MPI for the PAR installed in the OPR1000. The results of the preliminary analysis show that GASFLOW-MPI has the capacity to assess hydrogen behavior. The operation of the spray system increased the hydrogen volume fraction and halved the ...
GASFLOW-MPI codeCFD modelingHydrogen safetyDuring the severe accident in nuclear power plants (NPPs), hydrogen is generated due to the zirconium-water reaction and released from the breaks in coolant pipe forming a locally high concentration hydrogen cloud in the steam generator (SG) compartment, ...
In this work, the reverse meshing technology with two kinds of smoothing processes, the Marching Cubes smoothing approach and Laplacian smoothing approach, are developed for CFD code GASFLOW-MPI to reconstruct the CAD geometry from the previous simulation data, which free engineers from the tedious ...
Excellent agreements between test data and model predictions support the predictive capabilities of the combustion models in GASFLOW-MPI code. In Part II of the paper, the newly developed CFD methodology has been successfully applied to a first analysis of hydrogen distribution and explosion in the ...
