Objective: The aim of this investigation was to validate our numerical model of type B aortic dissection with our experimental results from a bench-top-model.

Methods: Various numerical meshes were constructed using a finite-volume based computational fluid dynamics (CFD) solver (ANSYS Fluent 15) to simulate pulsatile flow and pressure in dissected aorta models. The κ-ω Shear Stress Transport (SST) turbulence model was imbedded. All simulations were carried out for four cardiac cycles to achieve a periodic solution, and the results obtained in the fourth cycle were used in the validation.

Results: We validated the numerical results, for several tear size and location, with our experimental data. CFD results of type B aortic dissection with various tear size and location were strongly correlated with the in vitro results.

Conclusions: CFD tools have a potential role in evaluating different scenarios and aortic dissection configurations.
