Keywords: | Fluidstructure interaction; Hemodynamic wall parameters; Non-Newtonian fluids; Shear-thinning flow; Stenosis | Issue Date: | 10-Jun-2010 | Publisher: | Elsevier | Source: | Computers and Mathematics with Applications 3 (60): 572-590 (2010) | Abstract (english): | The aim of this contribution is to present recent results on numerical modelling of non-Newtonian flow in compliant stenosed vessels with application in hemodynamics. We consider two models of shear-thinning non-Newtonian fluids and compare them with the Newtonian model. For the structure problem, the generalized string equation for radial symmetric tubes is used and extended to a stenosed vessel. The global iterative approach to approximate the fluidstructure interaction is used. Finally, we present numerical experiments for some non-Newtonian models, comparisons with the Newtonian model and the results for hemodynamic wall parameters such as the wall shear stress and the oscillatory shear index. © 2010 Elsevier Ltd.
