...Joshua O. Taylor; Kory P. Witmer; Thomas Neuberger; Brent A. Craven; Richard S. Meyer; Steven Deutsch; Keefe B. Manning A summary of the CFD velocity and WSS results is presented in Table 1 . In addition, quantitative details of flow separation near the exposed thrombus surfaces...

... by Ahmed and Giddens ( 4 5 ) for steady flow, on which the comparisons carried out here are based, can be summarized as follows. The flow separated and recirculated immediately downstream from the throat ( Z = 0 ) . The turbulence level was still very low at Z = 2.5 and periodic...

... ), analytical approaches ( 12 13 14 ), and computational methods ( 15 16 17 18 ). The flow through stenotic vessels is characterized by high shear rates, flow separation, and possibly turbulence downstream of the stenosis. A central jet emanates from the throat of the stenosis creating shear layers, which...

... ( < 10 % ) of the axial wall shear stress (WSS) along the length of the stented model. The flow disturbance was characterized and quantified by the distributions of axial and transverse WSS, WSS gradients, and flow separation parameters. Normalized time-averaged effective WSS during the flow cycle...

... whereas the simulations indicate that flow separation continues at least until x = 10 D . This apparent early transition is confirmed by turbulent kinetic energy profiles in Fig. 3a , with maximum k values occurring between x = 2 D and 3 D . In contrast, the DNS profiles...

... of the flow separation on the stationary mass transport applying a permeability boundary condition at the water-permeable wall was analyzed using the finite element code FTSP. The results show an increase of luminal ADP surface concentration in the upstream and in the downstream tube of the sudden expansion...
