Improvement of fluid analysis capability and application to two phase flow

Uzawa, Ken

CCSE/JAEA promotes the research and development of the three-dimensional vibration simulator for seismic evaluation of a nuclear power plant (NPP) to further improve reliability of seismic safety of NPPs. We started R&D of fluid analysis capability as one of element technologies of the three-dimensional vibration simulator since last year. Especially, we have investigated a two-phase flow simulation code to analyze sloshing under earthquake. In this research, we achieved high parallel efficiency up to approximately 950.2 in parallel calculation using 1024 cores by improving an environment for massive parallel calculation. The technical feasibility for massive sloshing simulation including effect of turbulence is more or less established.
