Origination of detonation during multistage self-ignition

  • Published:
Combustion, Explosion and Shock Waves Aims and scope

Conclusion

The analysis performed shows that multistage self-ignition under known conditions can display the reason for strong shock and detonation wave generation. The wave excitation mechanism is associated with flame self-acceleration as, during the transition of combustion into detonation in tubes and consists of self-consistent motion of pressure and ignition waves. Realization of such a mechanism is quite probable in application to detonations in engines. The high-speed photography of a detonation explosion in an engine [11] actually, discloses the existence of self-ignition waves and records shock generation in local volumes of unburned parts of the charge.
