 note = {本稿では，様々な複雑構造の中を流れる多相流，とりわけ衛生陶器の水の流れを解析するために開発された高性能計算手法について述べる．微小気泡や飛沫，薄膜流れを再現するために，大容量計算メッシュにおいて計算時間を短縮する計算手法を提案する．直交格子と境界不整合領域分割法をGPUクラスタに適用することで，計算量の低減，GPUによる計算の加速および実用的な並列化効率を達成した．衛生陶器のシミュレーションでは，実現象に即した高精度な結果を得られた．, This paper presents a newly developed high performance numerical model to simulate multi-phase flows in various complex structures especially for sanitary wares. In order to reproduce numerous small bubbles, droplets and thin water films, the computational code has been built so as to be able to efficiently use large scale parallel processing and GPU-acceleration techniques. Particular efforts made in the present work include the combination of structured grids and non-conformal domain decomposition method, overlapping of data communication for CPU/GPU-coexisting systems, as well as GPU implementations. Satisfactory parallel scalability and GPU acceleration performance for large-scale simulations has been achieved. High-fidelity numerical results have been obtained in real-case applications for sanitary ware products.},
