Abstract

Limited measurements of flow characteristics within artificial blood pumping chambers have been reported in recent years by methods of particle streak photography, hot film anemometry, and laser Doppler anemometry. This study employed a single channel, pulsed ultrasonic Doppler velocimeter (PUDV) to measure instantaneous velocity distributions within the pumping chamber of a left ventricular assist device (LVAD). Instantaneous velocities have been decomposed into periodic mean and turbulent fluctuating components from which estimates of Reynolds stresses within the core of the flow and mean shear stresses along the wall of the chamber have been obtained.
