Abstract:
Extensive data on the length of the deflagration-to-detonation transition (DDT) are obtained for a wide range of explosive gas mixtures of acetylene, propane-butane, and methane with oxygen in tubes with constant and constricting cross sections. For the fuel-oxygen mixtures examined, it is found that the DDT length can be reduced to one tube diameter by using a volume system of obstacles with the size and distance between the obstacles being commensurable with the cell size of multifront detonation in these mixtures. The optimal mixture for deposition is found to be an explosive propane-butane mixture with oxygen in which the fraction of propane-butane is $\approx$25%.
