摘要

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.
