Effects of initial pressure on single spinning detonation in a square tube
Nobuyuki Tsuboi, Makoto Asahara, and A. Koichi Hayashi


Numerical researches for unsteady three-dimensional detonations in a square tube are presented in order to understand characteristics of single spin mode in a hydrogen / air gas mixture. The results show that the strength of the transverse detonation and the existence of the spin detonation depend on the initial pressure because the release energy in CJ state decreases as the initial pressure decreases.
