Double detonation drivers for a shock tube/ltunnel
- 58 Downloads
Recent progress on detonation drivers is reviewed. Performances of the forward detonation driver and backward detonation driver have been obsenred. To eliminate occurrenoe of a Taylor wave following the detonation wave in the primary driver and to improve the performance of the detonation driver, an additional backward detonation driver was proposed to attach to the end of the forward detonation driver. When the ratio of the initial pressures between the additional and the primary drivers becomes larger than or equal to a critical value, the Taylor wave will disappear, and thus a homogeneous driving gas with high pressure and high temperature can be generated. Furthermore, an over-driving detonation wave will be also obtained, which can increase the driving capability.
