| 摘 要： | 应用数值模拟和试验相结合的方法,研究了客车发动机后舱门开口封闭前后发动机舱内流场及温度场的变化。结果表明:后舱门开口封闭后,发动机舱内流场没有发生显著变化,冷却系统的冷却能力没有减弱。尽管原开口处、离合器附近略有温升,但不会对客车性能造成不良影响。

| Abstract: | The changes of flow field and temperature field of underhood before and after the closure of the back door opening of a bus engine cabin were studied by the numerical simulations and experiments. The results indicated that after the closure of the back door opening, there are no notable changes of the flow field inside the engine cabin. In addition, the closure does not lead to the decrease of the cooling capacity of the cooling system. However, the temperatures near the former opening of the back door and the clutch increased slightly. Nevertheless, the closure of the opening of the back door cannot cause adverse impact to the performance of the bus. |
