| Abstract(J) | 火花点火機関の燃焼予測精度向上には，初期火炎形成に影響する火花放電挙動の高精度な解析が不可欠である．本研究ではファン付き定容容器で火花放電過程を高速度撮影し，雰囲気圧力・流速の影響を解析した．さらに，実測値に基づくモデル定数の設定方法を検討し，数値解析の妥当性を検証した． Translation |
| Abstract(E) | Accurate analysis of spark discharge behavior, which influences initial flame formation, is essential for improving the prediction accuracy of spark-ignition engine combustion. In this study, high-speed imaging of the spark discharge process was conducted using a fan-equipped constant-volume chamber to investigate the effects of ambient pressure and flow velocity. Furthermore, the method for setting model constants based on experimental data was examined, and the validity of numerical analysis was evaluated. |
