摘要
目的研制一种便携式气溶胶喷雾器。方法借助计算机辅助设计(computer aided design,CAD)技术构建气溶胶喷雾器三维模型,并用计算流体动力学(computational fluid dynamics,CFD)技术对喷头进行仿真分析。结果设计出便携式气溶胶喷雾器产品造型,得到高速气体在不同位置的速度、压力随时间的变化情况,揭示漩涡分布特性,为喷头结构设计提供理论依据,减少了开发费用,缩短了开发周期。结论利用CAD技术为气溶胶喷雾器快速合理设计,结构参数优化提供了一种有效方法,过去主要借助于大量物理模拟实验方法处理的流体力学问题,现在大多数可以通过CFD技术加以仿真分析和解决。
