“…Literature reveals the experimental works include various scales ranging from the larger melt mass (Yamano et al, 1995;Huhtiniemi et al, 1999;Huhtiniemi and Magallon, 2001;Song et al, 2003) to single droplet study (Patel and Theofanous, 1981;Ciccarelli and Frost, 1994;Hansson et al, 2009a,b). Many fuel-coolant-interaction models were developed to improve the understanding of steam explosion and predict the results of experiments (Buchanan, 1974;Fletcher and Thyagaraja, 1989;Inoue et al, 1992). The fragmentation of the melt plays a crucial role in the process of steam explosion which determines the surface area of melt exposed and hence governs the heat transfer rate.…”
