Schematic drawing of the experimental setup: a centrifugal pump (EWP80, Davies Craig, Victoria, Australia) pumps fluid through a flexible tube (length 1m, inner diameter (ID) $\oslash$19mm) via a Y‐junction and two flexible tubes (6m, ID $\oslash$19mm) connected to rigid straight inlet pipes (2m, ID $\oslash$21.9mm) running along the MRI bed into the flow phantom. The closed loop is completed with a larger outlet pipe (1.5m, ID $\oslash$76.2mm), a reservoir and flexible tubing (11m, inner diameter $\oslash$19mm) connecting the reservoir and the pump. The FSI section consists of two inlets, a silicone filament attached to the wall and a single outlet. Further, equispaced data points for comparison of experimental data and numerical results on multiple planes are shown
