Carbon dioxide (CO2) geological storage traditionally involves capturing a CO2 stream from point source such as power station or cement, steel, natural gas processing plant, transporting it and compressing it, prior to injection supercritical phase into suitable reservoir overlain by cap-rock seal. One of the main perceived risks in is migration leakage buoyant through seal, via faults fracture...

Scour beneath piggyback pipelines laid on a sandy seabed is numerically investigated by solving two-dimensional (2D) Unsteady Reynolds-averaged Navier-Stokes (URANS) equations. The fluid flow and the sediment transport are resolved using two-phase Eulerian-Eulerian numerical solver SedFoam based open-source code OpenFOAM. A parametric study performed for different Shields parameters defined as ...
