Аннотация
Microexplosive fragmentation is a key phenomenon on which modern methods of secondary atomization of composite fuels are based in industry. The implementation of the corresponding processes makes it possible to reduce the size of secondary droplets by a multiple (from 10–15 to 100–200 times) relative to the initial values of the sizes of the parent droplets formed during spray disintegration. This study presents the results of studying the collective effects in the formation of secondary fragments as a result of microexplosive fragmentation of composite fuels. The characteristics of secondary fragments during microexplosive fragmentation of a group of three droplets of composite fuels are analyzed. Two fuel compositions were used: 90% diesel / 10% water and 10% diesel / 90% water. Using the Shadow Photography method, the typical sizes of secondary fragments, which are formed during the fragmentation of each of the three droplets in a group, are determined. The limiting distances (from 8 to 10 radii) between droplets are established, at which the integral characteristics of the fragmentation of a group of droplets satisfactorily correspond to the similar characteristics of the disintegration of single droplets. At smaller distances between droplets, significant differences in the characteristics of secondary droplets formed as a result of microexplosive fragmentation of composite fuels were registered.
