The main factor for integrity enhancement of the liquefied hydrocarbon gas pipelines is determination of outflow intensity from ruptured pipelines.

Aims and Objectives

Simulation of outflow of liquefied hydrocarbon gas from inclined pipelines.


Methods used are based on simulation of hydrodynamics equations of multiphase flow in quasistationary homogeneous equilibrium approximation.


It follows from the calculated data, that in the initial moments of time outflow from the full bore pipeline rupture in the horizontal section of the pipeline is more intense than in the full bore pipeline rupture at the bottom of the inclined one. The outflow from the top of inclined section takes an intermediate position.


There is developed a method of calculation of outflow from the orifice of ruptured sections of liquefied hydrocarbon gas pipelines.


Key words: inclined pipeline, liquefied natural gas, full bore rupture, outflow intensity, cumulative mass outflow.
