STATISTICAL ANALYSIS OF THE EFFECTS OF WATER DROPLETS COLLISION AT THEIR MOVEMENT THROUGH THE FLAME AS A SPRAYED LIQUID STREAM

The scheme, technique and results of experiments on statistical analysis of the effects of water droplets collision at their movement through the flame as a sprayed liquid stream are provided in this work. For receiving results of experimental research the modern high-speed video registration means, a cross-correlation video complex, and also the advanced methods and algorithms of information processing were used. It is established that errors of measurement of the water droplet sizes were no more than 2,1 %, speeds of gases and droplets — 3,4 %. Several characteristic modes of collision of droplets at the movement through a flame are revealed. The reasons of emergence of the revealed modes are established and the corresponding facsimiles are provided. Probabilities of approach of each collision modes (coagulation, crushing and scattering) are defined. The dependences illustrating the frequency of emergence of each collision mode and allowing predicting the collision modes are received. It is shown that on the basis of the revealed consequences of collisions of liquid droplets it is possible to choose parameters of its giving in a zone of a flame and an arrangement of sprays (relatively each other). The demanded crushing of a stream of droplets or their integration will be provided thus.
