Pressurized CO2 releases in the framework of carbon sequestration and enhanced oil recovery safety analysis: Experiments and model

The proposed modeling approach allows for the collection of details on the expansion degree of reversibility and heat transfer effects are inferred showing that ideal isentropic and isenthalpic paths are never matched. Its application well matches collected data and gives good prediction of the total discharge time. In addition, direct unobservable dynamics inside the closed tank are assessed, notably the instantaneous dense CO2 mass fraction and peculiar evolutions during phase change mechanisms in the liquid-vapor and solid-vapor domains.
