Outline of Final Research Achievements

In this study, we have experimentally studied an electrohydrodynamics (EHD) phenomena of ion flow fields that form nonuniform electric fields in gases and dielectric liquids. Specifically, the EHD phenomenon of a single gas-liquid two-phase fluid, in which a weak discharge is generated in the gas phase at the interface between the gas phase and the dielectric-liquid phase and the liquid flows at the same time, was investigated. The purpose of this research is to apply weakly ionized plasma to gas-liquid two-phase fluid based on the research results so far, to embody the quantitative evaluation of gas-liquid two-phase flow, and to develop the application of this EHD phenomenon. For that reason, in this study, quantitative analysis including measurement of the unsteady flow field, which is important from an engineering point of view, was carried out. That is, visualization measurement and quantitative analysis of gas-liquid two-phase flow including weakly ionized plasma were carried out.

Academic Significance and Societal Importance of the Research Achievements

気体・液体の2相流体における電気流体力学現象については、現象の発見、整理ならびに理論的な体系化がほとんど行われていないのが現状である。本研究の研究成果は、ラジカルを含む気液2相流体の電気流体力学現象の可視化とその定量的な解析について新たな知見を得たものである。
