An Experimental Set-Up for the <i>in Vitro</i> Simulation of a Physiological Pulsatile Flow in the Abdominal Aorta

In vitro experimental set-up is an important tool for investigating abdominal aortic aneurysm (AAA). Accurate reproduction of the physiological pulsatile flow waveform in aorta at various anatomic locations component these methods. The objective this study to establish generate a simulations aorta. was established by computer-controlled peristaltic pump and field circular straight pipe measured under conditions 2-dimensional particle image velocimetry system (2D-PIV). Experimental results show that provides with period 2 s, reasonable cross-sectional velocity distribution approximate inlet profile close human
