摘要

实验测量了电流体动力诱导气液两相流场的离子风。由于离子风沿气液界面的相互关系将产生电流体动力液体流动运动，因此需要新的方法来分析这种电流体动力气液两相流类型。在这项工作中，离子风沿着分层介质液体的测量是通过粒子图像测速法进行的，测量系统被用来从流场的时间序列数字图像中导出流速场，这些图像由一个用于计算机断层扫描的光片照射。给出了用烟线法获得的离子风流场的可视化图像，以及离子风速场的定性光学表征。从实验结果出发，讨论了离子风沿气液界面的特性。

Experimental study on ionic wind measurement of an electrohydrodynamically induced gas-liquid two-phase flow field by particle image velocimetry

Ionic wind of an electrohydrodynamically induced gas-liquid two-phase flow fields is experimentally measured. Since the electrohydrodynamic liquid flow motion will be created by an interrelation of ionic wind along the gas-liquid interface, new approaches are required to analyze this electrohydrodynamic gas-liquid two-phase flow type. In this work, ionic wind measurement along the stratified dielectric liquid was carried out by a particle image velocimetry where the measurement system was used to derive the flow velocity fields from time-series digital images of flow field illuminated by a light sheet for computer tomography. The visualization images of ionic wind flow patterns obtained by a smoke wire method, and the qualitative optical characterization of the ionic wind velocity fields is shown in detail. The ionic wind characteristics along the gas-liquid interface are discussed from the experimental results.
