INFLUENCE OF WATER DROPLETS DISTRIBUTION IN THE “WATER SHELL” ON TEMPERATURE IN FOLLOW MOVEMENT

Results of numerical investigations for influence of typical combustion deterrent — water spraying conditions on the temperature in the “water shell” follow movement are presented in the article. Estimates of water efficiency using at impact of water on the temperature in combustion zone are performed at difference schemes drops distribution in the “water shell”. Limited values of parameters which present distance between drops are determined for realization of minimal temperature. Dependences of dimensionless temperature in follow movement of “water shell” from ratio between the areas of evaporation and gross areas are presented for three heat and mass transfer model in the system water drops – high temperature gases which differ in the number of drops (two and five) and their location (series-parallel location to the motion direction). It is found that drops location in “water shell” plays a key role at the decrease of temperature in combustion zone. On the base of results variation of distances and location between drops it is shown that for effective decrease of temperature in follow movement of “water shell” appropriate to seriesparallel spraying. With increasing amounts of water which is directed on the extinguishing significant removal of adjacent droplets to increase the efficiency of liquid using.
