DYNAMICS OF EXPLOSIVE BOILING
要約
The results of a study of the dynamics of explosive boiling are presented. It is shown that the explosive nature of boiling at high-level metastability of the liquid is caused by formation of evaporation fronts. The effect of the test conditions on the dynamics of the fronts are investigated. The velocity of the evaporation front is not affected by the subcooling of the liquid, the manner in which the test section is heated (quasi-steady or unsteady), test section diameter and the orientation of the heating surface in the gravity field. A physical model of homogeneous and heterogeneous explosive boiling, which satisfactorily describes the dynamics of the evaporation fronts is presented. Certain transient processes, the onset of which is triggered by the formation of evaporation fronts are examined.
