旋转驱动装置流场数值模拟

为了让悬浮子弹能在空中达到一段滞空悬浮时间,设计了一种旋转驱动装置.首先介绍旋转驱动装置的工作原理,建立计算模型,然后对驱动装置进行流场仿真,改变驱动装置的出口直径及出口数,分析结构参数对驱动性能的影响.仿真结果表明:出口压力和出口速度相互制约,当气体通过驱动装置弯管区域时,气体压力和速度变化不大;其他条件不变,当驱动装置出口直径为2 mm,出口数为3时,提供的驱动力矩最大.

Numerical Simulation of Flow Field in Rotating Device

In order to keep suspension bullets staying in the air for a while, a rotary driving device was designed. Firstly introduces the working principle of the rotary driving device, calculation model was presented, numerical calculation was performed for flow field of driving device, change the outlet diameter and the outlet number of driving device, analysis the influence of driving capability on driving device. The simulation results show that the outlet gas pressure and the outlet gas speed are mutual restriction, when the gas through the driving device of pipe bending region, the pressure and velocity of gas are little change, other conditions are unchanged. When the outlet diameter of driving device is 2mm, the outlet number of driving device is 3, provided the maximum driving moment.
