MATHEMATICAL SIMULATION OF THE FORMATION OF THE SECONDARY FRAGMENTS OF LIQUID DROPLETS AS A RESULT OF THEIR COLLISION

A mathematical simulation of the formation of the secondary liquid droplets as a result of the collision of their primary droplets has been performed by the VOF method. The influence of diff erent factors on the conditions of fragmentation of liquid droplets and on their integral characteristics was investigated. The ratios between the surface areas of liquid droplets after and before their collision were calculated. It was established that the ratio between the surface areas of the liquid droplets of equal sizes is smaller than that of the liquid droplets having different sizes and that the centered collision of liquid droplets is most efficient. The critical Weber number of liquid droplets, an increase in which does not cause signifi cant changes in the characteristics of their secondary droplets, was determined.
