Numerical Investigation of the Transient Behavior of a Hot Gas Duct under Rapid Depressurization [PDF]
Science and Technology of Nuclear Installations, 2016 A hot gas duct is an indispensable component for the nuclear-process heat applications of the Very-High-Temperature Reactor (VHTR), which has to fulfill three requirements: to withstand high temperature, high pressure, and large pressure transient.

Depressurization of carbon dioxide in pipelines–Models and methods [PDF]
Energy Procedia, 2011 AbstractA model for two-phase carbon dioxide transport with phase transfer in pipelines is presented. The stiffened-gas equation of state is used for calculating thermodynamical properties. The convergence and accuracy of two numerical methods–a centred multi-stage (MUSTA) scheme and an upwind Roe scheme–are compared.

Depressurization of CO2 – a Numerical Benchmark Study [PDF]
Energy Procedia, 2012 AbstractA numerical benchmark study has been performed, comparing results from the OLGA pipeline simulator to data obtained using the multi-stage (MUSTA) centred scheme. The case considered is a depressurization of a pipeline. Care was taken to compare the same flow model and thermodynamic equation of state.

Depressurization of CO2 in a pipe:High-resolution pressure and temperature data and comparison with model predictions [PDF]
, 2020 The design of safe and cost-efficient CO2-transportation systems is an integral part of CO2 capture and storage (CCS) deployment. To achieve this, accurate transient flow models capturing the occurrence of gas, liquid and solid CO2 are needed.
