abstract = {<p style="text-align: justify;">Arterial diseases such as aneurysm and stenosis may result from the mechanical
and/or morphological change of an arterial wall structure and correspondingly
altered hemodynamics. The development of a 3D computational model of blood
flow can be useful to study the hemodynamics in major blood vessels and may provide
an insight into the noninvasive technique to detect arterial diseases in early stage.
In this paper, we present a three-dimensional model of blood flow in the aorta, which
is based on the immersed boundary method to describe the interaction of blood flow
with the aortic wall. Our simulation results show that the hysteresis loop is evident in
the pressure-diameter relationship of the normal aorta when the arterial wall is considered
to be viscoelastic. In addition, it is shown that flow patterns and pressure
distributions are altered in response to the change of aortic morphology.</p>},
