Abstract
In view of the research status at home and abroad on muzzle flow field,the effects of the artil-lery recoil movement on muzzle flow field are studied based on computational fluid mechanics theory. Two numerical calculation models with and without recoil movement were built by using axisymmetric Euler equations and finite volume method (FVM).The unsteady state numerical simulation was carried out by using computational fluid dynamics software and dynamic grid technology.By comparing the nu-merical simulation results with and without recoil movement,the results show that the pressure ahead of muzzle is decreased and the pressure behind the muzzle is increased.Artillery recoil has little effect on the force of the gun chamber.关键词
