Scarcity of cadaveric liver donors compared with the large number of patients with liver disease has been considered the main obstacle to use liver transplantation(LT)to treat hepatic malignancies and for the development of transplant *** is known that we are experiencing a true paradigm shift in the fundamental problem of transplantology,which is none other than the imbalance between donation and graft implants(1).Because the most common indication of LT in most countries[hepatitis C virus(HCV)cirrhosis]has started to decrease in the waiting lists(2,3).One might think that,for the first time in many years in Western countries,we could find a higher supply of organs than recipients for them.

A series of numerical sinmlations about a small scale （aspect ratio： 63.2） flexible pipe undergoing forced harmonious oscillation and vortex-induced vibration （VIV） have been taken into account. The wake hydrodynamics and pipe deformation were accomplished by ANSYS MFX solution strat- egy designed for fluid-structure interaction （FSI） problem with well-performed LES model. The configuration of structured mesh, multi-domain design, different mesh stiffness admeasured by User Fortran ensured that the numerical task was competent to deal with large deformation related to this case. The introduction of instantaneous amplitude definition and modeless component decom- position method （Chen and Kim, 2008） was helpful to reveal much more information from modal analysis. Most results from numerical simulation are generally consistent with those from model test （Choi and Hong, 2000） via the comparison between them. As supplementary to model test, visualization of the vortex wake was also provided. It has been proved that the forced oscillation doesn＇t only excite a complicated dumbbell-like wake pattern around the outer thimble, but also results in inner flow inside the PVC pipe. The velocity of the inner flow increases with the frequency of forced oscillation.
