On the Use of Minimum Film Boiling Temperature as a Criterion for Coherent Molten Metal-Coolant Interactions

Minimum film boiling temperature data obtained on 19- and 25-mm-diam spheres quenched in subcooled water are used to establish a relationship between the temperature of the hot molten material and the subcooled liquid for the occurrence of coherent thermal interactions. This relationship is then used to explain the various kinds of interactions observed in laboratory scale experiments conducted with molten tin, aluminum, steel, and glass.
