Abstract

A study was carried out focusing on the time and frequency domain characteristics. Dimensions were based on in-vivo data. Continuous Digital particle Image Velocimetry (CDPIV) was used to map the flow field of vascular junctions. High shear stress peaks and vortices were observed at the anastomosis toe. Flow reversal or separation was Reynolds (Re) parameter dependent. The flow profile and spectra were dependent on graft angle and elasticity. Better host-graft match resulted in less flow disturbances and flatter spectral distribution.
