基于VOF模型，利用Flow3D软件模拟了墨滴生成和断裂过程。与实验结果对比发现，墨滴分裂时墨水的粘度和表面张力对主副墨丝的形成具有很大影响；表面张力是所研究现象的驱动力，驱动电压对墨丝尾部的速度没有影响。

Ink drop formation and break off processes were simulated using Flow3D based on VOF model. Comparison was made with experiments. The results showed that viscosity and surface tension of ink has great influence on formation of main and secondary tails of ink drop; surface tension is the driving force behind most of the phenomena; the driving voltage has no impact on the tail-end speed.
