Outline
The critical initiation energy and critical tube diameter of C2H2-O2-Ar mixtures were measured in the experiment. The relationship between explosion length, which is theoretical calculated from critical energy, and detonation cell size as well as critical tube diameter was analyzed. The relationship between critical initiation energy and induction zone length was also investigated for each mixture. The results show that, for C2H2-O2 mixtures, a parametric relationship between explosion length and cell size is R0=26λ, however, this function is changed to R0=37.3λ and R0=54.8λ when 50% and 70% argon diluted, respectively. The relationship between critical tube diameter and explosion length is R0=2DC. The results indicate that detonation has stable one-dimension ZND structure when argon dilution up to 70%, and a linear relationship is found between critical energy and the cube of induction zone length.
