MATHEMATICAL MODELING OF BINARY COLLISIONS OF INHOMOGENEOUS PARTICLES OF LIQUIDS IN A GAS MEDIUM

The authors have presented results of mathematical modeling of collisions of inhomogeneous droplets of liquids (nonmixed two-fl uid droplets and emulsions) in a gas medium between each other. A study was made of the infl uence of a set of factors on the conditions and integral characteristics of disintegration: of the temperature of the external medium, the concentration of the steam, and the Weber number. The obtained results have shown a satisfactory correlation with experimental results. It has been established that the ratio of the areas of the evaporation surface after and before the interaction as a result of the collisions of inhomogeneous droplets corresponds to the range 0.8–2. It is the central collision of droplets that is the most effi cient. Critical values of the Weber number were established above which the ratio of the areas of evaporation surfaces of the droplets after and before the interaction S1/S0 remains constant, in practice
