Анализ чувствительности модели транспортировки газа по морским газопроводам к изменениям параметров модели

Research output

Abstract

Basic approaches to defining the coefficient of hydraulic resistance and the total heat transfer coefficient between the gas and the ambient in the model of an unsteady nonisothermal gas flow through an offshore gas-pipelines are considered. Model sensitivity to variations of these coefficients is illustrated by the charts, demonstrating influence of these coefficients on the basic flow characteristics. The coefficient of hydraulic resistance and the heat transfer coefficient calculations for one from test variant of gas transmission are given. The calculation method of these parameters from the experimental date, enabling to provide the validity of model of the unsteady nonisothermal gas flow through a sea gas pipeline when calculating certain pipeline is suggested.
