FLUID-STRUCTURE INTERACION IN HEMODYNAMICS
Fluid-structure interaction (FSI) is a multiphysics coupling between the laws that describe fluid dynamics and structural mechanics to consider both the interaction of some movable or deformable structure with an internal or surrounding fluid flow. Fluid-structure interaction (FSI) simulations are coupled CFD (fluids) and FEM (mechanics) cases. I supervised master thesis of engineering students where we studied the aortic fluid-structure interaction between FEA and CFD in order to analyse the behaviour of the fluid-structure interaction system. We analysed the formulations of non-newtonian fluids for the blood viscosity (Casson, power Law, Carreau-Yasuda, Quemada, etc.) and the formulation for non-linear materials to define the hiperelasticity of the blood vessels (Neo-Hookean, Mooney-Rivlin, Yeoh, Demiray, Holzapfel, Fung, etc.) in a healthy artery and in one with an aneurism.
These works were done in cooperation with Servei d’Angiologia i Cirurgia Vascular, Centre Hospital Universitari Joan XXIII, Tarragona and in the supervision of bachelor and master thesis of students from the Universitat Politècnica de Catalunya
