[Abstract]:According to the basic principle of computational fluid dynamics (CFD), the key parameters of injector, such as nozzle distance, mixing section diameter and mixing section length, are numerically simulated by using FLUENT software. The influence of ejector parameters on ejection coefficient is obtained. Based on the simulation results, the injector structure of the gas gun is optimized and applied to the corresponding gas gun. The optimized gas gun was tested and compared with the improved one. The number of decibels increased by 10 and the shortest time interval needed for continuous explosion of the gas gun was shortened. The research method has important reference value for improving the performance of gas gun.
