Andreas Chrysolouris

Early Stage Researcher 05

My name is Andreas Chrysolouris and I am from Athens Greece. I have graduated from the School of Mechanical Engineering in the National and Technical University of Athens (NTUA), in which I chose the specialization of Air and Ground Transport Vehicles. There I had the chance to emphasize a lot at fluid mechanics as well as computational methods. At the end of my studies, I did my Diploma Thesis on an optimization case of an airfoil with the use of a Fluid Structure Interaction (FSI) simulation. After I have finished my studies, I saw the MeDiTATe project as the perfect opportunity to further my studies, while also gaining experience in an industrial environment. Also, this project presents a chance for me to work in the biomedical field, while at the same time focusing on subjects I am well acquainted with. Currently I am working at ESI, as the ESR05, on the modeling of the blood flow in the aorta in an FSI simulation.

I am a PhD student at NTUA since the October of 2021. The subject of my study, as the ESR05 of the MeDiTATe project, is the modeling of the formation of the aneurysm in the aorta with the use of Computational Fluid Dynamics running on GPUs for the unsteady simulation of the blood flow and Structure Mechanics for the flexible wall of the aorta. Also, the couple of the two aforementioned software, for the Fluid Structure Interaction simulation of the aneurysm as well as the adaptation of the mesh used in the study. Finally, a big data analysis will be implemented to ensure the validity of the results. Since the beginning of my PhD five months ago, I was trained on both the CFD software PUMA (provided by NTUA) and the CSM software VPS (provided by ESI) and I have developed a coupling between the two, in order to perform an unsteady FSI simulation. In addition to that, numerous benchmarks have been studied to ensure the results of those simulations. Currently I have three months remaining at ESI under the instructions of Dr. Argiris Kamoulakos and afterwards I will move to Athens for eighteen months at NTUA under Professor Kyriakos Giannakoglou, who is also supervising my PhD, with two secondments at TVGH and RBF.
