Research output: Contribution to journalArticlepeer-review


The flow field inside an innovated ventricle assist device (VAD) was experimentally and numerically evaluated. Continuous sequences of experimental images, followed by their calculated velocity and vorticity transient fields, were obtained as animated presentation of the distensible VAD. Results were used to validate CFD simulations. Once validated, the CFD results provide a detailed 3D and time dependent description of the flow field, allowing the identification of stagnation or high shear stress regions.
