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.
