- Abstract
- Experimental investigations of the effect of the fuel type, composition of the combustible mixture, geometry of the combustion system and concentration of the suppressing agent were investigated in a two-sectional 50 mm i.d. detonation tube. Depending on the initial and boundary conditions, fast flames, quasi-detonations, Chapman-Jouguet detonations, and over-driven detonations were obtainable as possible modes of combustion. Each of such combustion modes constituted a reference state for further determination of the dynamic characteristics of the suppression processes.
