摘要
为了观察压力波形态对液滴压电喷射行为的影响.基于Bogy的压力波传递理论,简化了压电喷射模型,对水滴在不同压力波形态下的压电喷射过程进行了数值仿真,并对水滴的变形过程进行了分析.分别探讨了电压脉冲大小与宽度对水滴喷射行为的影响.结果表明随着电压脉冲大小和宽度的增加,液滴直径增加,而液滴喷射速度先增加后减少.通过合理的控制电压脉冲大小与宽度,可以有效的控制好压电喷射液滴的直径与速度.
In order to wordy the effect of pressure wave form on the droplet formation of piezoelectric ejection.The droplet piezoelectric injection model is simplified by the Bogy＇s pressure wave transferring theory.It takes water as the simulation objective and analyzes the forming process of water droplet through the numerical method.The influence of voltage pulse size and width on the water droplet injection behavior is investigated.There are some conclusions from simulation results as follows： With increasing the voltage pulse size and width,the droplet diameter will increase and the droplet velocity will reduce after first increase.These results indicate that the piezoelectric jet droplet diameter and speed are effectively controlled through the reasonable control of the voltage pulse size and width.
