The present thesis work aims to investigate and analyze the results obtained from the implementation of a low-cost set-up to perform PIV analyzes. This test-bench consists of an optimization of the one proposed in the Artery in Microgravity (AIM) project, that aims to investigate the effects of microgravity on coronary haemodynamics. The data acquired from the performed experiments were analyzed with two different algorithms, PIVlab and Optical flow (OF), in order to be able to make a comparison between the two methods. The coronary artery phantoms reproducing a healthy condition and a stenotic one were individually inserted into the hydraulic circuit.
