Comparison between Womersley’s solution and non-Newtonian 2D axisymmetric CFD simulations: velocity profiles and relative errors. In order to validate Newtonian assumption of the Womersly’s solution velocity profiles were drawn (1st column) at time steps t = 0 s, 0.2 s, 0.4 s, 0.6 s and 0.8 s (not presented). Graphs present two solutions: The local velocity for each method (left part of the graph); The dimensionless velocity profiles i.e. the local velocity divided by maximum velocity (right part of graph)—solid lines CFD simulations, solid lines with bullets Womersley’s solution. The 2nd column presents relative errors between both methods for velocity profiles. Rows from up to down present patients from 1 to 5.
