Presenter: Alexandra Metallinou Log, Research Scientist, SINTEF Energy Research
In this webinar, former NCCS PhD student Alexandra Log will present her work on rapid depressurization of CO2 in pipes. Correctly predicting the CO2 flow during a rapid depressurization is key to estimate pressure forces in an accident scenario, and the mass flow through valves and orifices. This is particularly difficult for CO2 transport in pipes, as the CO2 will most often be in a dense, liquid-like phase and depressurization will cause a phase change to gas referred to as flash boiling or flashing, which is not yet fully understood.
Alexandra will present key results from her thesis concerning this special phase-change phenomenon during rapid depressurization of CO2, highlighting experimental results, how to improve current flow models, and the fascinating underlying physics of flashing.
