  • Shock tubes can simulate blast waves in laboratory settings, offering advantages such as easily controlled parameters and varied measurement methods. It is widely used in the research of blast wave effects. However, in comparison to real blast, particularly in near-field blast, the blast waves generated by shock tubes has challenges in achieving shorter positive pressure durations and higher overpressure values. Through analysis of shock tube theory and numerical simulations, it has been determined that reducing positive pressure durations hinges on ensuring a swift catch-up by the reflected rarefaction wave with the incident shock wave. Similarly, increasing peak overpressure relies on enhancing the driving capability of the driving gas. Therefore, a conical cross-section driving approach is proposed to reduce the positive pressure durations, which allows the reflected rarefaction wave to catch up with the incident shock wave faster. By employing forward detonation driving technology and utilizing chemical energy to replace high-pressure air to increase the sound speed of the driving gas, high peak overpressure can be achieved at low detonation initial pressure. Numerical simulations show that under the same conditions of the incident shock Mach number (MS=2.0), the positive pressure durations can be reduced by nearly half and the device length can be reduced to nearly one-third by implementing the conical section-driven approach. Experimental results from the shock tube show blast wave characteristics, with peak overpressures ranging from 64.7 kPa to 813.4 kPa and positive pressure durations ranging from 1.7 ms to 4.8 ms. In blast wave simulation experiments, it is important to maintain the peak overpressure within a reasonable range to prevent the interface from reaching the test position. However, when the interface does reach the test position, it is possible to simulate the temperature field of the fireball in near-field blast waves. This research provides the necessary experimental conditions for evaluating the impact of near-field blast waves on injuries and investigating the protective performance of equipment.
