Deflagration-to-detonation transition (DDT) in a macroscale tube is investigated experimentally for stoichiometric ethylene–oxygen with O3 (ozone) addition. The effect of O3 addition on the DDT process is studied, including its dependence on initial pressure. This kinetic effect of ozone addition was investigated by examining the influence of ozone self-decomposition and ethylene ozonolysis on ignition delay time. It was found that O3 addition promotes DDT, while excessive O3 addition has a negative effect on DDT. Consequently, there is a critical O3 addition effect which depends strongly on initial pressure. For a lower initial pressure, kinetic effects of O3 addition are more obvious.
