碩士 === 國立成功大學 === 航空太空工程學系 === 84 === There are considerable evidences that hemodynamics may play
a role in thedevelopment and progression of arterial diseases.
Arterial walls in a cardio-vascular system are flexible,and its
elasticity determines the wavespeed in a tube. In addition , it
reduces the pressure loss and the turbulence intensity.Detailed
analysis of the pulsatile flow in elastic model may provide
us ainsight for the possible role of hemodynamics in the
initiation and pro-gression of vascular diseases.
In this thesis, we develop an effective and reliable numerical
calculationprocedure based on finite volume method and space
conservation law to simulatefluid flow in an elastic tube. Based
on this calculation procedure, we invest-igate the effect of
arterial elastivity on wall shear stress and flow resis-tance
in pulsatile flow field. Various parameters including degree
of wallmotion, frequence, flow wavwform and phase angle were
investigated.The resultsare compared with the rigid wall model.
