Simple transient release rate models for releases of pressurised liquid petroleum gas from pipelines

Large scale experimental data have been used to compare and derive simple mathematical models to describe the time varying release rate of pressurised liquid petroleum gas (LPG) from a ruptured pipeline. The models studied consisted of a single box, a single-node slip-flow and an empirical model. Th...

Description
Summary:Large scale experimental data have been used to compare and derive simple mathematical models to describe the time varying release rate of pressurised liquid petroleum gas (LPG) from a ruptured pipeline. The models studied consisted of a single box, a single-node slip-flow and an empirical model. The empirical model is based on data obtained using 100 metre long pipelines of internal diameters of 50 mm and 150 mm, from an experiment carried out jointly by BP Research and Shell Research Ltd. The empirical model was developed to describe the observed characteristics of the mass history of commercial liquid propane inside the pipe, namely the mass reduced approximately exponentially with time. While the single box model did not compare well with observed data, the single-node slip-flow model was found to produce exponentially time varying release rates.
