.... The governing equations with their corresponding boundary conditions were solved using CFD. It was found that halving the size of the artery diameter increased the wall shear value by more than 30%. In addition, the effect of increasing stenosis severity was more predominant than the size of the artery itself...

... that thrombosis in the Penn State pulsatile LVAD, on a polyurethane blood sac, is largely a function of the underlying fluid mechanics and may be correlated to wall shear rates below 500 s −1 . Given the large range of heart rate and systolic durations employed, in vivo it is useful to study the fluid mechanics...

..., and a wall shear rate greater than 500 s − 1 . Particle image velocimetry was used to compare the flow fields in the chamber of the 12 cc Penn State pediatric pulsatile VAD using two mechanical heart valves: Björk–Shiley monostrut (BSM) tilting disk valves and CarboMedics (CM) bileaflet valves...
