The thermo-hydrodynamic processes, preceding and accompanying the crisis of the film boiling regime of subcooled water on superheated liquid metal and solid surfaces, were studied by physical modeling. The main models of liquid-metal droplet fragmentation are analyzed. Experiments with liquid metal droplets …
