[3J09] Deepening Understanding of Ex-Vessel Corium Behavior by Multi- Physics Modeling
III. Physical property of liquid oxides measured by aerodynamic levitation
Keywords:Liquid oxide, Severe accident, Density measurement, Viscosity measurement, Aerodynamic levitation system
Physical properties, especially viscosity, of molten core materials are the key to evaluate the spreading behavior of the molten core materials. In this study, we built an apparatus which allows us to measure viscosity and density of molten oxides by combining aerodynamic levitation with oscillating droplet technique. Measurement was performed for simulant materials such as alumina.
