Flow Field Simulation and Efficiency Calculation of Muzzle Brake Based on ANSYS Fluent
The 713th Research Institute of China Shipbuilding Industry Corporation, 126 JingGuangZhong Road, Erqi District, Zhengzhou, Henan Province.
The development of advanced artillery needs to be combined with simulation means, so, traditional calculation method and the flow field simulation method was employed to calculate the efficiency of a largecaliber muzzle brake we designed, and the results achieved by these two methods were 47.8% and 49.3%, respectively. Further, the overpressure value 1 m away from the muzzle was obtained through flow field simulation, and the far-field overpressure value was calculated using blast wave attenuation equations. The result suggests that the blast wave from the designed muzzle brake has little harmful impact. This paper provides an intuitive calculation method of muzzle brake efficiency, also, it provides theoretical support for research of high efficiency muzzle brake and personnel protection onboard.
