The effect of initial pressure on the explosion behaviour of a stoichiometric CH4/O2/N2/CO2 mixture under oxy-combustion conditions was studied. The increase of initial pressure was demonstrated to significantly affect the explosion features. In particular, as the initial pressure increases, a transition was found from a deflagration mode to an explosion mode dominated by the severe combustion-induced Rapid Phase Transition (c-RPT) phenomenon.

Abstract
The effect of initial pressure on the explosion behaviour of a stoichiometric CH4/O2/N2/CO2 mixture under oxy-combustion conditions was studied. The increase of initial pressure was demonstrated to significantly affect the explosion features. In particular, as the initial pressure increases, a transition was found from a deflagration mode to an explosion mode dominated by the severe combustion-induced Rapid Phase Transition (c-RPT) phenomenon. In particular, when increasing the initial pressure from 1 bar to 3 bar, the peak pressure was found to increase from 12.5 bar to 200 bar.File in questo prodotto:
