Combustion of hydrogen‐oxygen‐diluent mixtures was carried out in a 2.3‐m‐diameter sphere with venting to a cylinder of 10.3‐m 1 volume. It was found that stoichiometric hydrogen‐oxygen mixtures with helium as the primary diluent led to detonation for all hydrogen concentrations above 20% by volume. Addition of small amounts (5 to 10%) of a secondary diluent such as carbon dioxide or steam suppressed detonation. Carbon dioxide, because of its higher molecular weight, was found to be a better detonation suppressant than steam. Transition to detonation was more difficult to achieve at 100°C than at room temperature.
