摘要:
含能材料直写技术可以解决MEMS微起爆器中微型炸药序列的装药问题。基于Fluent有限元软件，建立了CL-20含能墨水直写喷射模型，分别模拟了直写压力、针头直径和墨水黏度等因素对CL-20含能墨水喷射速度的影响。模拟结果表明：随着黏度增大，喷头中流体流动速度降低，同时,速度降低的幅度变小；压力增大，喷头中流体流动速度增大，且压力与速度变化的关系为正比关系；喷头直径增大，墨水流动速度增大，且随着喷头直径的增大，墨水流动速度增幅变大。
Abstract:
CL-20 energetic ink basing on direct writing technology was applied for micro-charge of the microdetonation sequence of MEMS micro-initiators. Direct writing of CL-20 energetic ink is the ink flow driven by nozzle pressure and rapid solidification. Direct writing pressure, needle diameter and ink viscosity had great influence on this process. In order to study the effect of these influence factors on jet velocity of CL-20 energetic ink, a simulation model of direct writing jet of CL-20 energetic ink was set up. Fluent, anumerical simulation software was applied to simulate the change of ink jet velocity under the different pressure, needle diameter and ink viscosity. Simulation results show that the fluid velocity in nozzle increased proportionally when the pressure rose. Moreover, the ink viscosity increased while the velocity fell and its range decreased. With the increase of nozzle diameter, the ink velocity rose and its range augmented.
