    • Abstract
  • Experiments on gas leaking rates in utility tunnels were carried out.Based on the experiments,gas mole distribution in utility tunnels was simulated using numerical method.The experiments were simulated with several classical turbulent models.Compared with experimental results,it is found that the gas mole fraction can be simulated by standard k-ε turbulent model,the results of which satisfy the demands of practical applications.
