Abstract

A complex of interrelated processes of heat-mass transfer with phase transitions at the ignition of liquid condensed substance by a low-power laser beam is investigated. Mechanisms of the heat-mass transfer processes are analyzed. The scale of influence of the power and the lasing range radius of the laser beam on the ignition characteristics is found. Critical conditions that do not enable the ignition in a system of liquid condensed substance film-laser beam-gas-vapor mixture are determined.
