Growth of the surface area of separated liquid fragments during high-temperature fragmentation of an inhomogeneous liquid drop

We have experimentally studied the formation of a droplet cloud during intense heating and subsequent explosive fragmentation of an inhomogeneous liquid drop. The experiments were performed with water drops containing graphite particles, which were heated in a flow of combustion products at a temperature varied from 600 to 1100 K. Three regimes of fragmentation of the inhomogeneous liquid drops have been observed, which are characterized by different total areas of liquid phase surface in aerosol clouds. Dependence of these regimes on the water/inclusion volume ratio and the amount of supplied heat has been determined.
