摘要: In this work we discuss the reliability of coupling among three-dimensional (3D) and one-dimensional (1D) models, that describe blood flowing into circulatory tree. In particular, study physical consistency 1D model with respect to 3D one. To aim, introduce a general criterion based on energy balance for proper choice conditions between models. We also propose way include in effect external tissue surrounding vessel its importance whenever is considered model. Finally, several numerical results real human carotids, studying different configurations highlighting best one view consistency.
