| Abstract(J) | 前報では，車両走行時の帯電による流れ変化を，流体・静電場・電荷輸送の3物理場連成解析により明らかにした．本研究では，タイヤ入力電荷，空気正イオン，中和状態の変動を考慮し，各要因が気流に及ぼす影響度を評価した． Translation |
| Abstract(E) | In the previous study, flow variations induced by vehicle electrostatic charging during driving were clarified through numerical analysis using a simplified step model that couples three physical fields: fluid flow, electrostatics, and charge transport. In this study, variations in tire-induced charge input, ambient positive air ions, and surface neutralization were further considered, and the influence of each factor on the airflow was evaluated. |
