摘要
结合湖南雪峰山特长公路隧道联络风道设计方案,采用了CFD(计算流体动力学)方法对轴流风机与联络风道的连接形式以及联络风道渐变段局部通风压力损失进行分析,以确定出较佳的连接结构形式,并计算出联络风道渐变段局部通风压力损失系数。
Based on the design of Xue feng Shan extra-long highway tunnel＇s connecting shaft, this article mainly used CFD to analyze the part of the connecting mode between fan and connecting shaft with the purpose to determine the relatively better connecting mode. And also this paper computed the ventilation pressure loss coefficient in the transition part of connecting part.
