Abstract
This report describes the development and testing of a highly-efficient method of coupling of a computational model of one-dimensional transient compressible flow in a ruptured pipeline with the Physical Properties Library (PPL) for evaluation of properties of various fluids, including hydrocarbons and their mixtures with other substances. The report summarises the basis of the mathematical model of transient flow in a pipeline, describes the method for calculation of the physical properties of the fluid using interpolation scheme as implemented in the flow model, and demonstrates the effectiveness of the proposed coupling method via simulation of decompression scenario of an ethylene pipeline.
