Experimental measurement and RANS modelling of multiphase CO2 jet releases

Abstract

International audience; The deployment of a complete carbon-capture and storage chain requires a focus upon the hazards posed by the operation of CO2 pipelines, and the consequences of accidental release must be considered as an integral part of the design process. CO2 poses a number of dangers upon release due to its physical properties, and modelling of the fluid dynamics of such poses a unique set of problems due to its unusual phase transition behaviour. Additionally, few experimental observations have been made with regard to CO2 releases to date, and so the physics and thermochemistry of such systems are not well understood. The current work has involved state-of-the-art mathematical modelling and experimental measurement to further advances in this area of research, and presented here are results from both. The performance of the mathematical models is elucidated with the use of the experimental data, and avenues for future developments are presented.
