Abstract

The results of investigations of electrohydrodynamic (EHD) flows using the schlieren method in the following systems of electrodes are presented: “blade–insulated edge blade,” “blade–two rods,” and “rod with perforated insulation coating–two rods.” Single-stage EHD pumps were designed on the basis of the obtained results. The pressure-flow characteristics of the pumps were studied depending on various factors. It was shown that the performance of the EHD pumps can be increased applying dielectric coatings to the electrodes. The maximum efficiency was obtained in the “blade–blade with insulated edge” system of electrodes, while the maximum static pressure was obtained in a three-rod system with a perforated insulation coating of the emitter. The advantages of a three-rod system were specified as regards to the improvement of the flow characteristics of the pump due to the parallel arrangement of the electrodes and the increase in the pump pressure when using multistage pumps with grid electrodes.

电流体动力流对传热传质过程强化的影响:第1部分。单级电液动力泵的流动及特性

本文介绍了用纹影法在以下电极系统中研究电流体动力学(EHD)流动的结果:“叶片-绝缘边缘叶片”、“叶片-两杆”和“带穿孔绝缘涂层的杆-两杆”。在此基础上设计了单级EHD泵。研究了各因素对泵的压力-流量特性的影响。结果表明，在电极表面涂上介质涂层可以提高EHD泵的性能。在“叶片-叶片带绝缘边缘”的电极系统中，效率最高，而在射极表面有穿孔绝缘涂层的三杆系统中，静压最大。三杆系统的优点是由于电极的平行排列和使用带有栅极的多级泵时泵的压力的增加而改善了泵的流动特性。
