Abstract
The transportation of pressurised CO2 using pipelines is a crucial element of the Carbon Capture and Storage chain; for their safe design the ability to accurately predict the consequences of a failure, the jet release and ensuing dispersion is essential. Such phenomena are commonly modelled in stages: jet expansion followed by atmospheric dispersion. For jet expansion modelling, both analytical and Computational Fluid Dynamic (CFD) models are available to predict the fully expanded flow conditions which are subsequently used as inputs in dispersion modelling. Although analytical models are computationally efficient, due to the lack of experimental data, their predictions have yet been verified. In this work, a conservation law based multiphase analytical model is constructed with a rigorous equation of state. The predicted flow variables at full expansion are then compared to those from the Shear Stress Transport k-ω CFD model. The quantitative comparisons between two models provide necessary verification of the application of analytical models in accidental release modelling.
