Boundary conditions for flow simulations of abdominal aortic aneurysms

TI Józsa, G Paál - International journal of heat and fluid flow, 2014 - Elsevier
Boundary conditions for abdominal aortic aneurysm simulations are problematic both on the
fluid and the solid side. In this paper improvements are suggested on existing methodology
in both respects. First, a derivation of a hyperelastic wall model is given, taking into account
the wall stresses at the diastolic instant. It is demonstrated that this model can be
approximated with a simplified linear wall model in the physiologically interesting range.
Then a new method for inlet and outlet boundary condition generation is introduced on the …
