| Abstract(J) | 車室内では，内装部品への空調気流の衝突やHVACシステムの気流導入方式に依存し複雑な流れ場となる．本研究では，車室内空気の効率的な換気のため，気流の吹出方向や換気方式を変化させた複数条件で車室内流れ場のCFD解析を実施し，固有直交分解により抽出した特徴的なモードを基に効率的な気流制御手法を検討した． Translation |
| Abstract(E) | In the vehicle cabin, the airflow from the HVAC system forms a complex flow field due to interactions such as impingement on interior components and the characteristics of the air-delivery configuration. In this study, CFD simulations of the vehicle cabin flow field were conducted under multiple conditions by varying the outlet direction and ventilation mode to achieve efficient cabin ventilation. Furthermore, Proper Orthogonal Decomposition (POD) was applied to extract characteristic flow modes, from which effective control strategies for improving HVAC airflow efficiency were investigated. |
