This product is mainly applicable to the tunnel: entrance section, change-over portion, basic segment and exit section.
本产品主要适用于隧道的：引入段、过渡段、基本段、出口段。
But the regions of local flow separation and distortion factor of the flow at the exit section are relevant closely to the yaw angle.
但是进气道内气流分离的区域和出口截面流场畸变指数却与侧滑角的大小密切相关。
It is fixed at exit section of the shell to reduce whirling current and thus reduce compact on the performance of instruments of lower reaches.
固定在壳体出口段，其作用是消除旋涡流，以减小对下游仪表性能的影响。
Uniform distribution of cavitation at the nozzle exit section is obtained by increasing length-diameter ratio and leads to the improvement of atomization.
从燃油空穴雾化理论的角度出发，空穴强度的提高以及在出口截面上的均匀分布都有利于燃油的破碎雾化。
Experimental results showed that the effective pressure distribution of the exit section was different and the flow friction decreased due to the influence of film bleeding.
结果表明：通道出口段存在气膜出流与无气膜出流情况相比出口段有效压力分布发生变化，并且使整个通道的流阻下降。
The increase of lobe diffusion angle results in the increase of velocity circulation at the lobe exit section, but it raises the mixing loss and lowers the pressure recovery coefficient.
扩张角的增加可提高速度环量，但是流动混合损失增加，总压恢复系数减小。
