Abstract: | Steady propagation of the boundary of a vapor cavity in a layer of a metastable liquid along the heater surface is considered.
The temperature and velocity of interface propagation are determined from the equations of conservation of mass, momentum,
and energy in the neighborhood of the stagnation point of the vapor cavity and the condition of stability of steady motion
of the interface. It is shown that a solution of these equations exists only if the liquid is heated above a threshold value.
The calculated velocity of interface motion and the threshold value of temperature are in reasonable agreement with available
experimental data for various liquids within wide ranges of saturation pressures and temperatures of the superheated liquid.
