基于CFD的燃料电池客车外流场数值模拟
|
摘要
以某燃料电池客车为研究对象,基于计算流体力学(CFD)对车身周围的流场、整车气动阻力进行了计算。计算获得的湍动能、速度场以及压力场表明,该燃料电池客车具有良好的气动特性,满足设计要求,为中国自主品牌客车造型设计提供了参考。
This paper takes a bus which runs by fuel cell as the research object. The flow field and the aerodynamic drag of the vehicle are calculated based on computational fluid dynamics( CFD). The obtained turbulent kinetic energy,velocity field and pressure field show that the current fuel cell bus has good aerodynamic characteristics,thus meeting the design requirement.This research provides a reference for the design of Chinese independent brand bus.
