| Abstract: | For cracking leakage of natural gas transmission pipeline, considering the boundary conditions that pipeline supplies gas continuously and broken leakage is in accordanee with exponential deeline rule according to time, the continuous leakage model is derived from the pipeline unsteady flow. The flow and pressure distribution along the length and the broken leakage flow calculation results are obtained when a large pipe burst occurs. |
