  1. Code for design on operating ventilation of railway tunnel

    鐵路隧道運營通風設計規范
  2. Then a one - dimensional unsteady incompressible flow with moving pollutant source model was proposed. the continuity equation, momentum equation and convection - diffusion equation were discredited using finite volume scheme. thus a software for predicting the air velocity and pollutant in railway double track tunnels was developed

    接著,根據雙線鐵路隧道運營通風的特點,建立了一維不可壓縮非恆定流和流動污染源的物理模型以及山相應的連續性方程、動量方程和對流擴散方程構成的數學模型;在此基礎上,利用數值計算方法,編制了一套雙線鐵路隧道運營通風的數值計算程序。
  3. By analyzing the relation between the train passing capacity and tunnel length as well as tunnel slopes the upper and lower limits for installing mechanical ventilation in railway double track tunnel have been determined, which provides science foundations for the formulation the ventilation design norm for railway double track tunnels in operation
