| dc.description.abstract | Розглянуто проблему аналізу балансу газу в об’єктах газотранспортної системи та
фактори впливу на точнiсть його встановлення. Показано, що проблему точності
розрахунку окремих балансових показників можна ефективно розв’язати, використовуючи
встановлені інваріанти математичної моделі руху газу. Проведені числові
експерименти підтвердили достатню точність запропонованого підходу. | |
| dc.description.abstract | A problem of gas balance analysis in the gas transportation system objects and the factors
of influence on the accuracy of its installation are considered. It is shown that the problem
of accuracy of calculation of the individual balance indicators can be effectively solved. For
this purpose, the invariants of the mathematical model of gas flow are used. The carried
out computational experiments have confirmed the sufficient accuracy of the suggested approach. | |
