| Outline of Final Research Achievements |
The purpose of this research was to consider visualization of gas-liquid two-phase flow fields accompanied by weakly ionized plasma flow, and its evaluation for EHD effects based on vapor-phase radical particles and the liquid-phase interface reaction. The experimental models were EHD flow fields where the weakly ionized plasma flow progresses to the interface of gas and liquid. For the results on visualization of EHD flow fields, the dielectric characteristics and electrical conduction characteristics in the gaseous phase and a liquid phase were evaluated. It was quantitatively urged for the conductivity of a liquid to have influence on the EHD phenomena. For the EHD effects of vapor-phase radical particles on liquid-phase interface reaction, the investigation into ionization action was conducted using the relative humidity of the mist as a parameter. These experimental results derived the knowledge that could consider effect of the ion polarity concretely.
