Abstract

The effect of water jet subcooling, dynamics and system constraint on FCls energetics in the CI mode with a water jet and molten thermite system was experimentally investigated by precisely measuring their mechanical energy release in the MUSE facility. Measured mechanical energy increased with increasing of jet subcooling in weakly constraint system but decreased in strongly constraint system. FCI energetics also increased with increasing of water jet velocity. These results suggest that the penetration and dispersion phenomena of a water jet inside the melt play important roles on determining FCI energetics. To understand fundamental physics of these phenomena and possible mixing conditions in the MUSE tests, a set of visualization tests with several pairs of jet and pool liquids in non-boiling and isothermal condition were carried out. Numerical modeling of the water jet penetration showed similar behaviors to those observed in the visualization test.
