It is established as a result of an experimental investigation that the quantitative and qualitative characteristics of nonstationary heat transfer depend substantially on the two-phase helium flux structure. A simple working model that permits estimation of the influence of the expended mass vapor-content and density of the heat flux on the dynamics of the process for a homogenized phase distribution (bubble and emulsion flow modes) is proposed to describe nonstationary film boiling. The fundamental heat transfer singularities under conditions of a dispersely annular flux structure are noted.
