Experiments werec conducted to investigate the triggering phenomenon in vapor explosion for various molten alloy pool depths and water droplet diameters in a droplet impingement system. The effect of the water droplet curvature Was found to be negligibly small when the droplet diameter is larger than 4.5mm. Vapor explosion conditions were identical for the depths ranging from 0.5 to 40mm. The length scale required in fragmentation and fine-scale mixing in the triggering event was considered to be less than 0.5mm.
