Abstract

Irregular detonations are supersonic combustion waves in which the inherent multi-dimensional structure is highly variable. In such waves, it is questionable whether auto-ignition induced by shock compression is the only combustion mechanism present. Through the use of high-speed schlieren and self-emitted light photography, the velocity of the different components of detonation waves in a \({\text{ CH}}_4+2\text{ O}_2\) mixture is analyzed. The observed burn-out of unreacted pockets is hypothesized to be due to turbulent combustion.
