Experimental investigation of explosive vaporization of liquids on the flat microheater

Abstract

The initial stage of controlled decay of metastable liquid was studied under pulsed heating on the surface of the flat microheater using the optical method of reflected laser beam. Four major stages of fluids explosive boiling and phase explosion on microheater were determined. The dynamics of filling the heater surface with the vapor phase, the lifetime of the main vapor bubble, and the satellite bubble are estimated.
