This paper reports on the behavior of shock triple points on the detonation wave propagating in the rectangular tube, which is obtained from the experimental observation and numerical analysis. Used gas mixtures are the equimolar gas mixture of acetylene and oxygen in the experiment, and the stoichiometric hydrogen and oxygen in the numerical analysis. However, if there are the specific number of shock triple points in the tube, the numerical analysis using finite difference method which is composed of semi-implicit MacCormack TVD scheme can reproduce the propagation behavior obtained by experiment. Therefore, the propagation mode of detonation is identified by geometry of emission points and emission trajectories of the experimental observation. And then, the detailed propagation mechanism of its detonation which is difficult to observe in the experiment has been revealed.
