Design Optimization of Blood Shearing Instrument by Computational Fluid Dynamics
Hemolysis Shear stress history Left ventricular assist device Computational fluid dynamics Optimization
2009/12/22
Rational design of blood-wetted devices
requires a careful consideration of shear-induced trauma
and activation of blood elements. Critical levels of shear
exposure may be established in vitro thro...
Enzymatic digestion of articular cartilage results in viscoelasticity changes that are consistent with polymer dynamics mechanisms
Enzymatic digestion articular cartilage results polymer dynamics mechanisms
2010/2/25
These results demonstrate that enzymatic digestion alters cartilage viscoelastic properties in a manner consistent with polymer dynamics mechanisms. Future studies may expand the use of polymer dynami...
