【摘要】 本文基于搭载主动进气格栅的燃料电池汽车,建立燃料电池汽车模型,利用STAR-CCM+计算分析搭载AGS的燃料电池汽车内外流场特性。搭载AGS后格栅叶片从全闭到全开的过程中,空气阻力系数从0.291逐渐增加到0.318。以120km/h高速工况为例,格栅叶片开度低于70度时,散热器进气量随着格栅叶片开度增大而增大,导致机舱内最高温度降低。而继续增大格栅叶片开度,散热器进气量及机舱内最高温度变化不明显。更多还原

【Abstract】 In this paper, based on the fuel cell vehicle equipped with active air intake grille, a fuel cell vehicle model is established, and the STAR-CCM+ software is used to simulate and analyze the internal and external flow field characteristics of the fuel cell vehicle equipped with AGS. When the grille blades are fully closed to fully opened after being equipped with AGS, the air resistance coefficient gradually increases from 0.291 to 0.318.Taking the 120km/h high-speed condition as an example, when the opening of the grille blades is lower than 70degrees, the intake air volume of the radiator increases with the increase of the opening of the grille blades,resulting in a decrease in the maximum temperature in the cabin. And continue to increase the opening of the grille blades, the air intake of the radiator and the maximum temperature in the cabin do not change significantly.更多还原
