The results of experimental studies of micro-explosion of two-fluid (water and rapeseed oil) droplets during heating in an air flow with a temperature of 250 to 450 oC are presented. As a result of video registration, an information database was obtained on the external surface area of the emerging aerosol cloud and the free surface of the liquid in comparison with the similar parameters of the initial drop. The dependences of these parameters on the heating temperature and the relative concentration (10–90 vol.%) of the combustible component in the droplet are established. The conditions for obtaining the asymptotic nature of these dependencies are determined.
