| Abstract: | A leakage and diffusion equation of overhead pipelines was established,and stable and unstable leakage processes when gas pipeline perforated were simulated.The flow rate of leakage was analyzed as well as effect of wind speed on the gas diffusion.The explosion limit of methane and poison range of hydrogen sulfide under different conditions were given,which is beneficial to determine the optimal time to implement rescue. |
