Abstract
Kinematic and dynamic characteristics of pulsating flow in a model of
human aortic arch are obtained by a computational analysis. Three-dimensional
flow processes are summarized by pressure distributions on the symmetric plane
together with velocity and pressure contours on a few cross sections for systolic
acceleration and deceleration. Without considering the effects of aortic tapering
and the carotid arteries, the development of tubular boundary layer with
centrifugal forces and pulsation are also analyzed for flow separation and
backflow during systolic deceleration.
