Simulation Of Gas Pipeline Leakage Using The
Characteristics Method

Abstract
The modeling of gas leakage for understanding the process of pressure reduction
and gas leakage rate of a hole is accomplished by zero-dimensional models of
the tank and pipe. These models of the tank and pipe are suitable for simulation
when the hole is very small or where there is a complete fracture. However, use
of these two methods or a combination of them is suitable rather when the
pipelines are very long. In zero-dimensional models the effects of complex
boundaries are also ignored. In this study, the pipeline leakage is simulated by
use of the one dimensional characteristics method. This model is perfect
compared with both pipe or tank models, or a combination of them, and we can
expand the simulation of gas pipeline leakage to the short pipelines and variable
boundary conditions. This is important in order to calculate the volume of gas
discharged from the pipelines when an accident occurs.
