Abstract: <br /> <br /> <br /> <br /> <br /> The modeling of gas flow through the pipe transmission is often done using an assumption that the flow is in a steady state, the condition for which the gas <br /> <br /> <br /> <br /> <br /> flow doesnt change in time. However, there are some situation for which this assumption is not reliable anymore. In this condition, we apply the transient gas <br /> <br /> <br /> <br /> <br /> flow model. <br /> <br /> <br /> <br /> <br /> By neglecting the effect of temperature, the transient gas flow model is comprised of continuity and momentum equations, together with the equation of state which <br /> <br /> <br /> <br /> <br /> uses some assumptions in order to simplify the problem. From these equations, we derive the pipeline equations which describe the distributions of pressures and <br /> <br /> <br /> <br /> <br /> gas flow rates at all time. To solve the pipeline equations numerically, the finite difference methods combined with Runge Kutta methods are used. The problem <br /> <br /> <br /> <br /> <br /> will next be extended to a pipeline junction, as a benchmark for the pipeline network. At the junction, we shall apply the Kirchoff Law. Then, the Newton <br /> <br /> <br /> <br /> <br /> Raphson method will be used in order to determine the pressure at the junction. To justify the model, simulations with hypothetical data are also provided.
