Thermal bleaching of aqueous aerosols by laser radiation

Conclusions

The modern state of the art about the bleaching process for aqueous aerosols permits its characterization as sufficiently complex. The theoretical deductions referring to the main and accompanying effects have been verified in experiments on radiation bleaching of artificial mists. There exists just a certain lack of clarity in the question of wave distortions in the bleached channel.

However, this survey refers just to the preexplosive modes of action. The self-action processes during realization of explosions of particles have been studied quite weakly. In connection with this problem gas-dynamic modes of particle explosions accompanied by the occurrence of shocks [31–33] are most interesting. Also of interest is a study of the fragmentation of aerosols due to local overheating of the particles. The effect in explosions of this kind is carried over into the water content mode, and the process as a whole can be described by the energy variable method. Bleaching under fragmentation conditions has been noted in [34].
