前置式客车发动机舱热风回流研究

Research on Hot Air Recirculation in Engine Cabin of Front-mounted Bus

前置式客车发动机舱通常会产生热回流现象,造成发动机冷却效果变差。本文利用CFD方法分析某前置式客车发动机舱产生热回流的机理,提出热回流解决方案并进行试验验证。

The engine cabin of front-mounted bus usually emerges the hot air recirculation,which results in the decrease of the engine cooling performance. This paper utilizes the CFD method to analyze the mechanism of hot air recirculation produced in engine cabin of a front-mounted bus,proposes the solutions to the hot air recirculation and does the experimental verification.
