• A series of experiments were carried out for small-scale vapor explosions in a "dropping" system using molten tin and water. Experimental parameters such as initial tin temperature, water temperature, ambient pressure and sample size of tin were varied over a wide range. The pressure of explosion, the rate of occurrence of explosion and the position of explosion were measured in detail. It is found that tough the vapor explosion has in general statistical characters, a delay time between tin-water first contact and explosion increases systematically with both water temperature and initial tin temperature. As a resul, it is concluded that the vapor explosion is closely related to transient boiling phenomenon, especially to the collapse of a stable vapor film around the molten metal.
