On the velocities of normal and deflagration burning of gaseous mixtures

Research output: Contribution to journalConference articlepeer-review

Abstract

In accordance with the classical one-dimensional detonation theory, the lower adiabatic branch of the energy release of the combustible mixture as the geometric locus of the final state points of the system also allows solution for combustion waves whose propagation velocity lies in the range from zero to deflagration speed. The velocity of the normal burning wave falls within this range, but the calculation is traditionally conducted with the help of the thermal theory of combustion (not within the framework of the theory of detonation). In this paper the conservation laws of the detonation theory were used for choice of a point of the final state for a normal flame. The analysis was carried out and estimates were given showing both the degree of compliance of the estimated and experimental values of flame velocities, and the degree of compliance of the qualitative behavior of these dependences on the main parameters of the mixture.
