Abstract

A hybrid large eddy simulation and immersed boundary method (IBM) computational approach is used to make quantitative predictions of flow field statistics within the Food and Drug Administration's idealized medical device. An in-house code is used, hereafter (WenoHemo™), that combines high-order finite-difference schemes on structured staggered Cartesian grids with an IBM to facilitate flow over or through complex stationary or rotating geometries and employs a subgrid-scale turbulence model that more naturally handles transitional flows (Delorme et al., J Biomech 46:207-436, 2013). Predictions of velocity and wall shear stress statistics are compared with previously published experimental measurements from Hariharan et al. (J Biomech Eng 133:041002, 2011) for the four Reynolds numbers considered.
