Highway Tunnel Longitudinal Numerical Simulation Of Ventilation

According to one-dimension common calculating theory of highway tunnel longitudinal ventilation, the author compiles the LVSRT program under the language environment of Matlab. The program consists of some simulation models which can be composed freely to meet the need of simulation analysis. The program has not only many kinds of computing function, but also good windows. It is used to the example analysis of ZhongLinag Shan Tunnel. The analytical process verify the program function and show the ingenuity and convenience of the program. Based on the CFDesign program of the FEM of the calculating fluid mechanics, the author calculate the incompressible internal turbulent to simulate three important parts of distributed losses, local losses and jet ventilation, and draw some profitable conclusions.
