摘　　要：应用Fluent6.3对带有圆盘空化器的火箭深弹阻力特性进行数值计算,得到火箭深弹阻力系数随速度及通气量的变化关系。结果表明:火箭深弹在水中运动时主要受到压差阻力及粘性阻力的影响,且压差阻力占总阻力的成分较大。安装圆盘空化器进行通气后,深弹受到的压差阻力得到明显改善;速度相同时,总阻力随通气量的增加先急剧减小后缓慢增加。火箭深弹的理论计算结果与水洞试验结果基本一致.The drag characteristics of the rocket depth with disk cavitator was simulated with computational fluid software Fluent 6.3.and then the relationship curve between drag coefficient of the rocket depth charge with the speed and ventilation was obtained.The simulation results show that the main influence factors of the rocket depth charge underwater navigation are the larger proportion pressure drag and the smaller proportion viscous drag.The pressure drag of the rocket depth charge was reduced evidently with the increase of the ventilation when it was ventilated.At the same speed,with the increase of the ventilation,the total drag sharply decreased first,and then slowly increased.The experimental results of disk cavitator are consistent with theoretical results in the paper.
