The process of pressure reduction and gas leakage rate (discharge characteristics) of a hole has so far been accomplished by utilizing some zero-dimensional models. In these models, the effects of complex boundaries are ignored. The major aim of this study is simulating the process of pipeline gas leakage by the aid of a modified one-dimensional characteristics model. This model, beside the possibility of modeling the impact of leakage on one-dimensional compressible flow, benefits from introducing a variety of boundary conditions to flow zone. In this approach, hole is considered as an orifice, which makes a path for gas to release in a lower pressure ambient. Also, in this study, the effects of four kinds of boundary conditions at the ends of the pipeline on gas discharge characteristics are investigated.
