Effect of carbon dioxide (CO2) suppression on explosive limits of methane

Theoretical models to predict the upper/lower explosive limits of a mixture composed of hydrocarbon and inert carbon dioxide (CO2) are proposed in this study. It is found theoretically that there are linear relations between the reciprocal of the upper/lower flammability limits and the reciprocal of...
