IN THE FORM OF FILM VAPORIZATION

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.
