Jet Flow Simulation of CL-20 Energetic Ink
摘要
Abstract
CL-20 energetic ink basing on direct writing technology was applied for micro-charge of the micro-detonation 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.关键词
