Fluid-structure interaction of the aortic valve.
The aim of the project is to investigate the possible implementation of a numerical model of the aortic valve in a fluid-structure interaction (FSI) framework and to quantify its impact on the aortic flow.
The aortic valve is the valve that connects the left ventricle to the aorta. In a healthy cardiovascular system, it behaves more or less like a binary valve, and is either open or closed. The impact of the heathy valve on the flow is usually minimal. As a result, a common simplification in the modeling of aortic flow consists in neglecting the presence of the aortic valve. However, for pathological scenarios (like an aortic stenosis) the aortic valve might have an impact on the flow, generating perturbations that propagate along the aorta. In this project, the idea is to explore and investigate the various techniques used in literature to account for the presence of the aortic valve in computational models.

The goal of the project is to implement a computational method to model the impact of the aortic valve on the flow and quantify the importance of considering the aortic valve to model flow in the aorta. The work should be carried on the open source finite volume solver OpenFOAM or the open source finite element solver FEniCs (see [1] for an example & for the source of the thumbnail image).

**Possible Tasks**
- Segmentation of aortic MRI scans
- Meshing aortic or tubular geometries
- Using a CFD software to solve laminar or turbulent flows
- Implementing a FSI method to take into account the aortic valve
- Quantitatively analyze the effect of such FSI method on the aortic flow
