Conclusion
Thus such important characteristics as the time of formation of the bleached zone and the efficiency of the bleaching process with thermal action of continuous CO2 laser radiation on a water aerosol have also been studied in detail in the theoretical and experimental investigations that have been conducted.
Quantitative values of the characteristics indicated have been obtained in the absence of wind transport of drops for different values of the power density of the acting radiation in the range 12–80 W/cm2.
It has been shown that convective fluxes, induced by the radiation, greatly retard the process of bleaching and decrease its efficiency.
The effect of thermal in homogeneities on the conditions for transmission of laser beams in the action zone of continuous CO2 laser radiation has been investigated. The magnitude of the refraction and thermal self-focusing of the laser beam have been estimated quantitatively.
The characteristics of the transmission of laser beams through a water aerosol under conditions of explosive thermal and nonthermal breakup of drops have been examined. Values of the parameters determining the conditions for transmission of radiation in the presence of an explosion have been obtained.
The investigations of physical processes, accompanying the transmission of intense laser beams in water aerosol accompanied by thermal and nonthermal actions, have shown that for practical application, thermal methods for bleaching cloud formations, in view of their high efficiency compared to nonthermal methods, are most promising [36].
