| 概要 | Japan aims to deploy next-generation sodium-cooled fast reactors, with gas entrainment posing a critical challenge to reactor operation. At the Japan Atomic Energy Agency (JAEA), we developed a two-phase Lattice Boltzmann Method (LBM) for simulating gas entrainment, validated using the quasi-steady vortex problem. It demonstrated high accuracy and efficiency, achieving simulations with up to 400 million cells on multi-GPU systems. We will extend the validity and capability of our two-phase LBM by addressing dynamic scenarios such as wake-vortex-induced gas entrainment and implementing Adaptive Mesh Refinement (AMR). We aim to establish a robust, efficient tool for reactor design and safety analysis. |
