Використання коефіцієнту стисливості газу при комп’ютерному моделюванні нестаціонарних режимів течії газу

Abstract

This work is devoted the issue of the impact of choosing an approximation formula for the gas compressibility factor on the distribution of gas flow parameters: mass consumption, pressure and temperature in the non-stationary regime of gas flow along a pipeline has been considered. The obtained results can be applied to calculate the transient regimes of gas flow during emergency and abnormal situations.
