Vapour Bubble Collapse Model to Describe the Fragmentation of Hot Liquid Melts in Water

摘要

Some dropping experiments carried out to study the fragmentation of melts in melt-water reactions are discussed. In addition, an experiment on vapour film behaviour on spherical surfaces is reported. A vapour bubble collapse model which should describe the fragmentation of a melt in the liquid state is developed for a mathematical description of these experiments. The surface enlargement of a lead melt is calculated using simple relationships for the bubble dynamics. Important experimentally observed results agree qualitatively with the predictions of the model, whilst different results can be attributed to the inadequate development of the model. It would seem useful to refine the model. (Atomindex citation 11:570394)
