Abstract: The cause for abnormal increase of shock Mach number in a combustion driven shock tube had been discovered. The experimental results show that the capabilities of gaseous detonation driver are stronger than to combustion driver which bring about a great advance in detonation driving technique. Using a dumping section to eliminate the reflected high pressure of the detonation wave and utilizing double detonation driver to eliminate completely the Taylor wave following the detonation wave makes the backward and forward detonation drivers usefulness. The backward detonation technique is utilized still to prolong the test duration for a shock tunnel.-
