摘要:
为控制重载列车在不同长度的隧道内会车过程中引起的煤粉尘污染和资源浪费，以神朔铁路蛇口峁隧道为研究对象，基于ANSYS Fluent的Realizable k-ε湍流模型和动网格技术，对C80型运煤车以70 km/h车速在长度为L1（隧道长度L＜列车长度l），L2（l≤L＜2l），L3（2l≤L）的隧道会车过程风流压力场和风流速度场特征变化规律进行模拟研究。研究结果表明：隧道受限空间尺度对车身周围风流场分布有较大影响；列车相遇过程中，长度为L1，L2的隧道口处风流主要来源于驶入列车的车身，长度为L3的隧道口处风流主要来源于车身及列车尾流；列车并行时，长度为L1，L2，L3的隧道内车身周围负压力分别约为隧道外车身周围负压力的1.8倍，6.5倍，7.0倍；列车相离过程中，长度为L1，L2，L3的隧道内列车尾流负压力分别约为隧道外列车尾流负压力的1.6倍，2.4倍，4.1倍。根据模拟研究结果进一步分析重载铁路隧道扬尘规律，并提出控尘措施。研究结果可为后续控制铁路隧道煤粉尘污染和减少资源浪费的具体措施提供一定理论基础。
