Abstract
The simulator for multicombustion-gas jets injection is designed to study the gas-curtain generation characteristics by multicombustion-gas jets during the underwater gun launch process. The expansion process and interaction process of combustion-gas jets in the liquid are studied under the different injection pressures and nozzle diameters by means of a high-speed camera system, and then the turbulent mixing during the merging are numerically discussed. The experimental results indicate that the gas-curtain is formed by the turbulent mixing process and the turbulent mixing process is enhanced with the injection pressure increasing before gas-curtain forms. In the initial phase, the expansion velocity of the gas-curtain is affected by the center jet and the final expansion velocity is determined by the side jets.
