Numerical Analysis and Optimization Research of Short Duct Flow Field of Outlet and Inlet in Highway Tunnel

SHI Ping1、2,XIA Yong-xu1(1.Highway Institute,Chang'an University,Xi'an 710064,China;2.Communication Planning and Design Institute of Hubei Province,Wuhan 430051,China)  
When the sending and exhausting shaft is ventilated,short duct flow may occurred between outlet and inlet,which will baffle air exchange in highway tunnel.By applying finite-element method,this paper analyzed three-dimensionally the flow field of short duct,the result shows that the back flow in short duct exists always;the range L of back flow can be reduced obviously as the length of short duct is increased;considering reducing energy dissipation and satisfying the air quality,the proper length of short duct should be 65 to 80 meters.
