摘 要：
为探究不同射流温度对隧道风机纵向间距的影响,以某公路隧道实际工程为研究背景,运用FLUENT软件,模拟分析了当开启一组射流风机时,不同射流温度对隧道内速度场和温度场的影响。结果表明:在不同射流温度工况下射流风机纵向控制间距的模拟数值与经验公式的计算结果吻合,验证了模拟方法的正确性;射流温度越高,隧道内温度衰减趋势越明显,诱导段的风机轴线纵向速度越低,从而不利于气流组织的发展。

摘 要：
In order to explore the different effects of temperature on the tunnel jet fan longitudinal spacing,taking the actual engineering of a highway tunnel as the research background,the influence of different jet temperature on the velocity field and temperature field in the tunnel is simulated and analyzed by using FLUENT software when a set of jet fans are opened.The results show that the simulated value of longitudinal control distance of jet fans is consistent with the empirical formula under different jet temperature conditions,which verifies the correctness of the simulation method.The higher the temperature of the jet is,the more obvious the trend of the temperature attenuation in the tunnel is and the lower the longitudinal velocity of the fan axis in the induced section is,which is not conducive to the development of the airflow.
