摘要
研究了爆炸参数与信道湍流强度的关系.采用参数分离方法将大气折射率结构常数分离为常数项、含压强项和不含压强项,在此基础上研究爆炸产生的冲击波对周围压强的影响,最终得出大气折射率结构常数与炮弹装药量和冲击波传播位置的关系.仿真结果显示大气折射率结构常数随冲击波传播距离指数衰减,并且在10～20m范围内1 000kgTNT爆炸产生湍流介于弱湍流与中湍流之间.
The relationship between the explosion parameters and turbulence intensity of channel are in- vestigated. The method of parameter separation is proposed to separate air refractive index structure constant into constant term,pressure term and non-pressure term. On this foundation, the influence of pressure around by the shock wave, which is produced by fixed-point explosions is studied, and the rela- tionship between air refractive index structure constant and shell ammunition quantity and the spread po- sition of shock wave is obtained. The simulation result shows that the air refractive index structure con- stant is reducing along with the spreading distance of shock wave, and at the range of 10 to 20 meters, turbulence produced by 1 000kg TNT is between the weak turbulence and middle turbulence.
