Our research group focused on an ignition method of the EILs by applying a voltage. Previous Studies have theoretically reported the possibility of ignition of ADN-based EILs and experimentally demonstrated the ignition. However, appropriate operational conditions have not been established due to a lack of understanding of the ignition process and phenomena. Therefore, the objective of this study was understanding the ignition process and phenomena based on the results of voltage applied experiments (image, temperature and current measurement). In this experiment, a voltage was applied to a droplet of ADN-based EILs, and the behavior of droplet was filmed by a high-speed camera, while temperature and current measurements were made simultaneously. The voltage application process is divided into four phases based on current behavior. It was revealed that the amount of power required for the transition from Phase 1 to Phase 3 remained constant under different experimental conditions. Established a method for measuring ignition delay time. Furthermore, it became clear that the ignition delay time could be reduced by lowering the resistivity of the sample., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA2230017003, レポート番号: JAXA-RR-22-006}, title = {電圧印加時におけるADN系イオン液体の可視化および温度・電流同時測定}, year = {2023} }
