Experimental Study of Bypass of Critical Locations in Relation to Vessel Wall Shear Stress
Original language description
The contribution deals with the investigation of the flow parameters in the bypass junction in a human body and it is aimed at the localization of areas with critical Wall Shear Stress (WSS) values and thus at the anastomosis shape optimalization with reference to the WSS. The experimental measurement of WSS was carried out by the help of hot film anemometry and obtained results were compared with results from numerical simulations and with results from Particle Image Velocimetry (PIV). Both experimental and numerical results point to the same area which is characterized by a low value of WSS and unfavourable WSS behaviour. This area is situated approximately x/D = 1,3 behind the Toe on the side opposite the Floor and x/D = 0 on the floor side. This x/D value is affected by graft angle and by the ratio of host artery and graft diameters - the smaller angle the longer x/D ratio for minimal value of WSS.
