Depressurization of CO2 in a pipe: Effect of initial state on non-equilibrium two-phase flow
Log, Alexandra Metallinou; Hammer, Morten; Deng, Han; Austegard, Anders; Hafner, Armin; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2023)It is key in several industrial applications to accurately describe rapid depressurization of liquid and dense phase states. Examples include refrigeration systems, nuclear reactor cooling and capture and storage (CCS). ... -
Experiments and modelling of choked flow of CO2 in orifices and nozzles
Hammer, Morten; Deng, Han; Austegard, Anders; Log, Alexandra Metallinou; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2022)In order to accelerate the deployment of capture and storage (CCS), engineers need experimentally validated models, among other things, to predict the mass flow rate in process equipment and flow restrictions like valves, ... -
A flashing flow model for the rapid depressurization of CO2 in a pipe accounting for bubble nucleation and growth
Log, Alexandra Metallinou; Hammer, Morten; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2023)Flashing flow is encountered in many industrial systems involving nozzles, valves and decompression of vessels and pipes. In the context of CO2 capture and storage (CCS), the design of safe and efficient CO2 transportation ... -
HLLC-type methods for compressible two-phase flow in ducts with discontinuous area changes
Log, Alexandra Metallinou; Munkejord, Svend Tollak; Hammer, Morten (Peer reviewed; Journal article, 2021)In this work, the Harten-Lax-van Leer Contact (HLLC) approximate Riemann solver is extended to two-phase flow through ducts with discontinuous cross-sections. Two main strategies are explored regarding the treatment of the ...
