Abstract:

Results of theoretical model calculations of sound generation by water drops in the process of their evaporation and explosive fragmentation have been presented in this paper. Explosive fragmentation of drops has been shown to decrease the efficiency of conversion of the light energy absorbed by drops into the acoustic wave energy. This fact is primarily explained by the decrease of vapor influx into air due to the decreased rate of drop evaporation after its fragmentation. The available experimental data on acoustic signals produced by exploding water particles have been interpreted.
