Abstract:
The development of gaseous detonation driving techniquesand its behavior are reviewed. It is proposed to use adumping section to eliminate the reflected high pressure of the detonationwave and to use variable cross-section to mitigate the detrimentaleffect of Taylor wave. Accordingly, the driving modes of backward detonationand forward detonation can generate testing gases with high enthalpy andhigh pressure. The double detonation driver not only can eliminate theTaylor wave following the detonation wave completely and improve the drivingquality of the forward detonation, but also constitutes a new way to furtherimprove the driving capability.
