T1 Experimental and Theoretical Investigation of the Process of Initiation of Vapor Explosion on a Solid Semispherical Model. Part 2. Experiment JF Heat Transfer Research JO HTR YR 2001 FD 2001-04-01 VO 32 IS 1-3 OP 8 AB On the basis of the analysis of the experimental data, a physical model of the initiation of a vapor explosion has been developed. The following stages of the process of an explosion-like transition from a film to a bubble boiling on a semi-spherical model immersed in water are calculated: the incipience of the Kelvin-Helmholtz instability of a vapor film; growth of the instability amplitude and the collision of the crests of liquid waves with a surface; extension of the region of collisions due to the propagation of capillary waves generated in recoil; the cooling of the model of the temperature below the critical one and collapse of the vapor film; superheating of the surface layer of liquid that came in contact with the model and the expansion of the formed vapor layer resulting in the generation of a descending liquid jet. The estimates obtained demonstrate the qualitative and quantitative agreement with experimental results.
