COMBUSTION AND DETONATION DEVELOPMENT REGIMES IN GAS-MIXTURES

A method is proposed which allows use of a unified model for numerical study of combustion and detonation in homogeneous gas mixtures, inclu ding transient processes, as well as determination of conditions under which the combustion-detonation transition develops. The mathematical modeling results presented permit classification of flow regimes whic h develop in the fuel mixture upon forced ignition of a portion of the mixture. The calculations show that the qualitative character of proc ess development depends significantly on the values of the defining pr oblem parameters: the kinetics of the reaction, energy liberation, flo w turbulization during motion, etc.
