Steady-State Model and Its Application in Natural Gas during Transportation in Pipeline

This paper built the forecasting model that can predict the temperature, pressure and flow along natural gas pipeline according to pipe flow equations. Improved Euler method is used to solve these equations. The changes of gas velocity and temperature along pipeline are included to improve the accuracy and precision of the simulation. A MATLAB program has been developed to implement the algorithm. Comparisons between this program and the professional gas pipeline simulation software show that the proposed algorithm in this paper has higher accuracy.
