摘要
阐述了低温流体静电积聚的形成过程和相关的影响因素,总结了流体静电研究的数值方法以及一些特定形状容器的简易理论模型。通过比较电荷量、电位值以及电流大小测量方法的不同,评价静电测量方法的可靠性,讨论了除传统接地法之外的方法以抑制静电的产生,并针对流体特性有效地进行静电耗散。
The formation mechanism of accumulation of static electricity in cryogenic fluid was expoun- ded and the relevant influencing factors were summarized. Numerical methods for studying the static elec- tricity phenomenon in fluids were presented to analyze some simple theoretical models of containers in spe- cific shapes. By comparing measurement methods with different electric charge, voltage and current, the re- liability of the measurements could be assessed. The methods besides conventional grounding to suppress the generation of static electricity and to dissipate electrostatic effectively were also provided.
