BUBBLE GROWTH RATE AND PHENOMENON OF DEGENERATE BOILING OF A FLUID IN THE FORM OF FILM VAPORIZATION A. R. Dorokhov and V. I. Zhukov UDC 536.423.1 An analysis of results of an investigation of vaporization of a thin fluid film under vacuum is presented. The vaporization process has basic features characteristic of bubble boiling of a fluid, except for formation of bubbles. This makes it possible to classify the phenomenon as degenerate boiling of a fluid in the form of film evaporation during which local thinning of the layer takes place and funnel- and crater-shaped structures are formed. Funnels and craters are vapor sources with different powers. Dependences of the bubble growth rate above vapor sources of both types that generalize available experimental data are obtained.
