Моделювання нестаціонарних режимів по ділянці трубопроводу великого діаметру зі змінним перерізом

Abstract

This work is devoted to a problem statement of a mathematical modelling of non-stationary regimes on large diameter pipeline section with variable crosssection. The pipeline segment viewed as a combination of two pipes, connected through an adapter. To improve the accuracy of thermal process description during gas expansion in large diameter pipes, the Joule-Thomson effect is proposed to be incorporated into the mathematical model. This approach can be applied to model non-stationary regimes in challenging areas and enhance the efficiency and safety of gas pipeline operations.
