浅水プール中の壁面衝突液体ジェットにおける渦状液膜挙動に関する研究

抄録

To contribute to accident managements of water-cooled nuclear reactors, we quantified the interfacial behavior of a vortex-like flow in a wall-impinging liquid jet in a shallow pool in a liquid-liquid system by extraction of the feature points on the interface. We also considered forces acting on the liquid film and its interface in the vortex-like flow on the basis of the interface shape and its feature points. To investigate the mechanism of the vortex-like flow as the next step, we considered that quantification of the forces acting on the interface and fluid in the flow is useful.
