摘要:
为揭示抽水蓄能电站倾斜转弯隧道火灾烟气蔓延与顶棚温度衰减特性，依托某抽水蓄能电站施工支洞，在自然通风下使用热释放速率约为0.5，2.0，3.0 MW的甲醇池火开展一系列全尺寸实验，研究温度时空演化特征、温度垂向分布特征、最大温升偏移长度及顶棚温度纵向分布，并基于Chilton-Colburn类似提出考虑坡度与曲率耦合效应的温度衰减系数修正模型。研究结果表明：2.0，3.0 MW下烟气蔓延速率对火源功率不敏感且近似匀速；最大温升偏移长度显著大于直线隧道；弯道与直道段顶棚温度呈2段指数衰减且温度衰减系数偏大，模型验证结果良好。研究结果可为抽水蓄能电站倾斜转弯隧道通风排烟设计与人员疏散策略制定提供实验参考与理论支撑。
Abstract:
In order to investigate the smoke spread and ceiling temperature attenuation characteristics of fires in inclined curved tunnels of pumped storage hydropower plants,a series of full-scale experiments are conducted in a construction access tunnel of a pumped storage hydropower plant under natural ventilation conditions,using methanol pool fires with heat release rates of approximately 0.5,2.0,and 3.0 MW.The experiments examine the spatiotemporal evolution of temperature,the vertical distribution of temperature,the offset length of maximum temperature rise,and the longitudinal distribution of ceiling temperature.Based on the Chilton-Colburn analogy,a modified temperature attenuation coefficient model is proposed that accounts for the coupled effects of slope and curvature.The results show that at 2.0 and 3.0 MW,the smoke spread rate is insensitive to fire source power and proceeds at an approximately uniform velocity.The offset length of maximum temperature rise is significantly greater than that observed in straight tunnels.The ceiling temperature in both the curved and straight sections follows a two-stage exponential decay,with temperature attenuation coefficients that are comparatively large,and the model validation yields satisfactory agreement.These findings provide experimental reference and theoretical support for the design of ventilation and smoke exhaust systems as well as the formulation of evacuation strategies in inclined curved tunnels of pumped storage hydropower plants.
