Abstract
This paper presents new data on the detonation parameters of lean, stoichiometric, and rich methane-oxygen (air) and hydrogen-oxygen (air) mixtures inhibited by nitrogen and carbon dioxide. By varying the ratio between the initial components, carbon dioxide was found to have a stronger inhibiting effect on the parameters of combustion and detonation products.
