... with steady flow) during parts of the cardiac cycle, but eliminated all flow separation during other parts. This combined with the fact that Robaina et al. [ 20 ] determined that areas subjected to intermittent flow separation and attachment showed the highest levels of platelet deposition would appear...

.... On the other hand, the RANS SST-Tran model also managed to capture important flow features (e.g., flow separation and reattachment) and velocity profiles similar to experimental data, giving credence that the comprehensive engineering correlations incorporated in the model could be applied to lower Reynolds...

... 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 result in recirculation regions bounded by the jet and the wall. The separated regions have low wall-shear stresses (WSS...

... ( < 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...

... flow separation flow simulation haemodynamics pulsatile flow turbulence Experimental and numerical evidence for irregular, transitional, and turbulent hemodynamic flows in both physiological (due to vessel curvature and bifurcations) and pathological (due to plaque-induced stenoses...

... indentation. Wall pressures were measured and flow visualization was performed to detect flow separation and reattachment. The channel flow was analyzed by Ikeda and Matsuzaki 5 with their channel flow model, which like most other one-dimensional models does not consider the particular shape of the channel...

... 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...
