Abstract

The aim of this investigation is to study numerically the hemodynamic effect of false lumen partial thrombosis of an aortic dissection for various tear size and configuration. The numerical model will be validated against the experimental results from a bench-top-model in the absence of thrombus. Various numerical meshes will be 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 Shear Stress Transport (SST) turbulence model will be imbedded. All simulations will be carried out for enough cardiac cycles to achieve a periodic solution, and the results obtained in the last cycle will be used in the validation. The effect of false lumen partial thrombosis for various tear size and configuration will be presented in this investigation. We anticipate that the presence of thrombus will affect significantly the pressure difference between the false lumen and true lumen as well as the flow pattern and wall stresses.
