Evaluation of thermal consequence in sodium fire experiment in two-cell geometry

Ohno, Shuji  

A liquid metal sodium leak and pool fire experiment has provided the transient temperature data measured in more than 100 positions for atmospheric gas and structures. The experiment was performed in an air-filled 2-cell geometry that was made by partitioning the room of rectangular cell with an opening between the cells. The analyses of the measured data clarified the basic characteristics of sodium pool combustion and consequential heat and mass transfer in the cells. The data also suggested several features of multi-dimensional thermal-hydraulic behaviors that occurred in the experimental geometry during the fire. The measured data are expected to be utilized for the validation study of numerical sodium fire analysis tools.
