Abstract
- Shock wave propagation processes of dual-source underwater explosion are researched. Basing on dimensional theory, the variation of peak pressure and specific impulse gain coefficient with dimensionless explosion distance and dimensionless spacing are analyzed. The results show that there are high-pressure coupling and low-pressure coupling regions in the shock wave field. The shock wave peak pressure and specific impulse are functions of dimensionless explosion distance, dimensionless spacing and azimuth. When the azimuth is 90, conclusions are as follows: when the dimensionless explosion distance is greater than 30 and the dimensionless spacing is greater than 2.48, the gain coefficient of shock wave peak pressure is stable at 30%~50%, when the dimensionless explosion distance is constant and less than 30, the gain coefficient of shock wave peak pressure is maximum in the dimensionless distance range of 9~13, and the specific impulse gain coefficient increases with the dimensionless distance in the range of 4.96~24.81.
