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