Preliminary experimental investigation on detonation wave ignition technique

To investigate the primary characteristic of detonation wave ignition technique, the experimental system of hydrogen/oxygen detonation wave ignition was designed. Experiments were executed on the condition of pressure 0.1-0.5 MPa and mixture ratio 1.6-9.4 at common temperature. Investigation was made on spreading characteristic of detonation wave in a tube and multi-run reduplication characteristic of detonation wave ignition technique. Results show that pressure above 1 MPa and temperature over 1300°C could be produced from lower gas pressure by detonation wave ignition technique, and the multi-run time difference is less than 0.3 ms.
