Abstract:

The question is examined of a possible model of the interaction of vapor bubbles and an inflowing fluid in the precritical region of thermal loads during nucleate boiling. The first approximation expresses a hypothesis on the possibility of interpreting the double-phase wall layer as a system of jets of fluid of irregular form, streamlined by vapor. The boiling crisis is treated as a purely hydrodynamic effect, the result of destruction of the stable existence of fluid formations in the vapor flux forming in the wall layer. The problem of the stability of the liquid-gas interface was examined analytically in a number of works. The application and development of this analysis to the boiling crisis resulted in a functional relationship, making it possible to take into account the effect of viscosity of the fluid on the critical loads.
