| 抄録(英) | Reducing aerodynamic drag is crucial to improve the efficiency of vehicles. In this study, the feasibility of releasing the cooling flow into wake region to enhance automobile’s aerodynamic drag performance was investigated. A realistic general vehicle model for aerodynamic study was used as an investigation target, and a parametrically optimized cooling ventilation duct which leads to vehicle’s base surface, including the radiator, was equipped to reduce the aerodynamic drag. Compared with the original sample in aerodynamic ideal configuration which shut out the radiator ventilation, the modified one shows a similar level of drag but with the cost of losing half radiator ventilation volume compared to the original model in baseline configuration. By comparing the flow field around samples during the optimization process and original model, the mechanism between the cooling flow which in wake region and the drag performance variation was primarily discussed. 翻訳 |
