Застосування методу характеристик при моделюванні нестаціонарних режимів течії газу по ділянці трубопроводу великого діаметру

Abstract

This work is devoted to the application of the method of characteristics in the mathematical modeling of non-stationary modes on a large-diameter pipeline section. It is proposed to use the Joule-Thomson effect, which manifests itself for pipes of large diameter. Equations for the direction of the characteristics and differential relations on the characteristics are obtained. The results obtained can be used to calculate non-stationary regimes depending on the initial conditions.
