Do generalized Newtonian mathematical models differ significantly from Newtonian models in simulating blood flow in patient-specific cerebral aneurysms?
Generalized Newtonian models for blood flow in cerebral aneurysms yield similar results to each other but differ from standard Newtonian models in computational simulations.
Generalized Newtonian models converge on similar aneurysm hemodynamics; leaves open whether they outperform Newtonian assumptions in clinical CFD.
Two different generalized Newtonian mathematical models for blood flow, derived for the same experimental data, are compared, together with the Newtonian model, in three different anatomically realistic geometries of saccular cerebral aneurysms obtained from rotational CTA. The geometries differ in size of the aneurysm and the existence or not of side branches within the aneurysm. Results show that the differences between the two generalized Newtonian mathematical models are smaller than the differences between these and the Newtonian solution, in both steady and unsteady simulations.
