Mathematical model for calculation of the fuel combustion into the constant volume cylindrical chamber taking into account deflagration to detonation transition are suggested. Model takes into account heat transfer, convection, irradiation and finite rate chemistry reactions depending on temperature and pressure. It was shown that initial pressure and fuel type exerts significant influence on the combustion mode, particularly on deflagration to detonation transition that plays key role in choosing regimes at thermal-pulse deburring.
