Abstract

Combustion is also involved in explosions for both peaceful and military purposes. In the past decades; there has been a considerable progress in understanding combustion processes and regimes of the combustion propagation. This review focuses solely on explaining various phenomena of premixed combustion: (1) flame propagation; (2) detonation waves; (3) when and how explosions occur; (4) the transition from flame to detonation and (5) when ignition of combustion involves phases of deflagration or detonation. Additionally; the paper will include a discussion of what pollutants are produced during combustion and how clean and efficient combustion can be achieved. Examples of typical combustion scenarios; including flames propagating in tubes; closed chambers or engines are overviewed; along with events of the thermonuclear Supernova.

Results obtained during past decades on the dynamics of flames; the understanding of the nature of burning and mathematical descriptions and numerical modelling of combustion are outlined. I shall talk about such prominent scientists as Yakob Zel’dovich and Lev Landau who were at the origin of modern combustion theory and made fundamental contributions to the understanding of combustion.
