WebWe present computational fluid dynamics (CFD) results of virtual fractional flow reserve (vFFR) calculations, performed on reconstructed arterial geometries derived from a digital phantom (DP). The latter provides a convenient and parsimonious description of the main vessels of the left and right coronary arterial trees, which, crucially, is CFD-compatible. … WebThe combined effects of flow resistance and stratified flow lead to the above variation pattern of cement displacement interface. When the casing is in the middle or the eccentricity is small, the flow resistance between the gaps in the annulus does not show much difference, and the stratified flow of two-phase fluid plays a major role.
