The debris spreading-cooling model has been developed which makes possible a multiplex heat and mass transfer analysis with flow spearhead and melt front transportation in open spaces. While the flow analysis capability without energy transportation analysis was verified using a water spreading experiment in Part (I), the capability with energy transportation and solidification analysis is verified by comparing with results from a thermal-hydraulic experiment for spreading of a stainless steel melt in the present study. The comparisons show good agreement between model and experimental results for the spreading process, and the calculated cooling and solidification processes are physically reasonable. In addition to this, the model functions for the three-dimensional natural convection with simultaneous spreading, melting and solidification are tested. The present model is useful in various industrial fields involving behavior of melt in open spaces.
