PIV was performed using a TSI (TSI Inc, Shoreview, MN) system. To ensure minimum image distortion, the outer surfaces facing the camera and the laser are flat and orthogonal to the acquisition and the laser beam axis, respectively. Seeding the flow with fluorescent particles while cutting off laser light reflections with a color filter further improves PIV quality.

Assessment of the flow field using flow visualization (left), PIV (middle), and CFD (right) at 1 L/min; inflow split: 60/40 IVC/SVC; outflow split: 30/70 left/right lung. Flow visualization dye is injected from the SVC. Height (h) is measured from model anterior. The CFD simulations were run under the same conditions and assumptions as the experimental setup, namely incompressible, laminar flow with steady inflow conditions, and rigid, but smooth vessel walls.
