| Abstract(J) | 本研究では，Ahmedモデルと呼ばれる簡易車両モデルに，連続噴流を用いた流れ制御手法を導入し，横風による後流パターンや空力特性の変化を抑制した．追い越し車両モデルが生じる現実的な横風条件下の数値解析を行い，この制御法の効果を検証した．数値解析の結果，追い越し中の車両モデルの空力特性は低抵抗，低揚力状態を維持するように制御された． Translation |
| Abstract(E) | In this study, a flow control method using continuous jets was introduced to a simplified vehicle model called the Ahmed model to suppress changes in wake patterns and the aerodynamic characteristics caused by crosswinds. The effect of the continuous jets was numerically investigated in a realistic crosswind condition on the road, caused by the overtaking vehicle model. The result of the numerical analysis showed that the continuous jets controlled the aerodynamics of the vehicle model to maintain the low drag and lift state while the model was being overtaken. |
