Abstract
Recent advances in the area of computational analysis of blood flow devices are presented. Flow simulation techniques relevant to blood pump design based on stabilized finite element formulations and a deforming-mesh space–time approach are outlined, and the results are compared with experimentally-obtained data for a rotary blood pump. Flow prediction is augmented by a strain-based morphology-tensor numerical model capable of quantifying mechanical blood damage. For more accurate representation of blood constitutive behavior, a stabilized finite element formulation for viscoelastic fluids of Oldroyd-B type is also under development. Taken together, this collection of numerical techniques has the potential of significantly improving predictive capabilities of computational fluid dynamics (CFD) during the development stage of blood flow devices.
