| Abstract | The forward mode is usually chosen to achieve high-enthalpy flows for a detonation-driven shock tunnel. In this paper, the dual-ignition system was developed to burst a metal diaphragm without its fragmentation under the forward operation mode. The influence of delay time on the test conditions of the high-enthalpy shock tunnel was investigated numerically. Results showed that the delay time should be set exactly, or it would affect the performance of the shock tunnel using the dual-ignition forward driving mode, i.e., the effective test or the stagnation temperature. The larger the delay time, the closer the CJ plane propagates to the primary diaphragm, the better consistent with the forward mode. |
