Abstract:
The influence of inert and chemically reactive additives in the form of microdrops on the dynamics of a single bubble filled with an active gas mixture and collapsing under the action of a shock wave is considered. The development of a reaction during formation of the mixture is analyzed for instantaneous and dynamic evaporation of drops with allowance for various phases of their injection $t_{inj}$. It is shown that in instantaneous evaporation, an increase in the fraction of gaseous argon in the $\mathrm{H}_2+\mathrm{O}_2$ system raises the final temperature of the system under cryogenic conditions, lowers it under ordinary conditions, and causes appreciable oscillations of the values of $\gamma$, heat release, and molecular weight. It is noted that there are values of $t_{inj}$ and $D_0$ at which the final temperature of the mixture decreases practically to the initial temperature.
