Analysis of TROI-13 Steam Explosion Experiment

Table 1

Selected experimental results from TROI facility [5]. SDM is the mean Sauter diameter of the debris, 𝑋_<0.425 mm is the mass fraction of debris particles whose size was lower than the sieve size of 0.425 mm, SE indicates whether a spontaneous steam explosion occurred or not, 𝑝_dynamic is the dynamic pressure peak, and F is the dynamic force peak at the test vessel bottom.
