G0601-5-6 Outbreak of Ultra-high Pressure Underwater Shock Waves using Gas Imploding Detonation

Abstract

The imploding detonation of a propane-oxygen mixture was applied to generate underwater shock wave in a water pipe of 60mm inner diameter. We investigated imploding detonation waves in an approximately cone-shaped combustion chamber having a maximum inner diameter of 400 mm. The experimental results show that maximum pressure at the water pipe exit was 690 times higher than the initial gas pressure. We found that we could generate the water pressure more than 500MPa in a pipe repeatedly.
