Abstract

Abstract: The ventilation effect of jet fan is the study object of this paper.After comprehensive analysis of various factors on ventilation jet fan vertical effects，the important influence about the height of jet fan and the angle between the jet fan axes and the tunnel axes for the ventilation effect is optimized based on the Computational Fluid Dynamics（CFD） theory.Fan 1120 as an example to simulate the optimize results，gets the optimal installation height and angle degree by Three-dimensional modeling tunnel solidworks，reaching a highway tunnel ventilation fan jet effect of optimization.The simulation result shows there are an optimal installation of the jet fan and a high degree of fan axis with the tunnel axis angle，which are decided by the parabola characteristics appearing the influence trend.The Simulation result provides the scientific basis to the highway tunnel ventilation design.

摘要： 以公路隧道射流风机通风效果为研究对象，综合分析影响射流风机纵向通风效果的各项因素，利用计算流体动力学（CFD）理论，对射流风机的安装高度、风机轴线与隧道轴线之间的夹角进行优化仿真分析。以1120型风机为例通过隧道三维建模技术Solidworks进行效果优化仿真，得到最优安装高度及夹角，达到了公路隧道射流风机通风效果的优化。仿真结果表明射流风机的安装高度与射流角度对通风效果的影响趋势呈抛物线特征，存在一个最优的射流风机安装高度和风机轴线与隧道轴线的夹角，为公路隧道通风设计提供了科学依据。
