Abstract
The paper is devoted to the numerical and theoretical analysis of the mechanisms of generation and amplification of shock waves in the process of unconfined flame propagation. Two basic mechanisms of shock wave generation corresponding to the linear and nonlinear stages of hydrodynamic instability development are distinguished. The role of thermoacoustic instability in shock wave amplification and the establishment of the conditions for deflagration-to-detonation transition is demonstrated on the example of a highly chemically active mixture.
