Modelling and simulation of the CO₂-transport

Pipelining is currently the solution to transport the voluminous CO₂ emissions from large power plants to geological storage sites. In the frame of the CCS-technology the material transport through pipelines, elbows and complex geometries is playing a central role. The flow is three-dimensional, multiphase, multi-component and mostly turbulent, and its complete characterization is very challenging. Especially, the coexistence of large and small scale structures is not complete understand. Aim of the project is to conduct numerical studies of the CO₂ transport through pipelines to achieve an extensive characterization from hydro- and thermo-dynamical point of view. By means of 3D flow simulations the material transport in specic components of the CO₂-process chain is studied. The numerical simulation results are also used for verifcation, further development and specifcation of the currently used experimental measurement techniques. For the successful treatment of the numerical work package, fully 3D time-dependent simulations are carried out for the determination and characterization of the multiphase and multi-component flow fields.
