Researches in the gasdynamics of explosion and reacting systems

Conclusions

The papers presented at the colloquium and the results from personal discussions indicate that the numerous applications of combustion and explosion processes in rocketry, industrial technology, and in safe handling of fuels during transportation have meant that researches on the gasdynamics of explosive phenomena are being vigorously pursued in the USA, France, Britain, Japan, and other industrially developed countries. Particular interest attaches to evidence presented at the colloquium on methods of calculating shock-wave parameters for large-scale explosions of gases and fuels, together with definition of the critical conditions for detonation propagation in chemically active media, as well as analysis of turbulent mixing and combustion in gases and heterogeneous systems. In particular, turbulent mixing, combustion, and detonation have major applications in laser engineering, and it has been shown, for instance, that separate excitation and turbulent mixing of nonequilibrium high-temperature gas flows can substantially improve the efficiency and optical characteristics of high-power gasdynamic laser systems. Efficient optical methods of diagnosis for combustion, detonation, and explosion processes have been developed in the USA and France, and these deserve attention and further study for use in experimental research. This applies particularly to laser Raman spectroscopy and laser holography.

The next (Sixth) Colloquium will be held in August 1977 in Stockholm, and the President of the Organizing Committee for that colloquium was confirmed as Professor P. A. Person.
