THESIS

Title: Pulsed Flow in a Curved Vessel – Flow Modification by Focused Acoustic Streaming

Joint PhD Program between ENIM and University Lyon 1

Supervisors: Professor Maher Ben Chiekh (LESTE- ENIM) & Professor Jean-Christophe Béra (University Lyon 1, LabTAU Inserm Lyon)

Date of first enrollement :  November 2024

Topic: This research focuses on analysing the wall stress fields, including the gradients and fluctuations of these stresses, in a model configuration of the external iliac artery. Experimental flow measurements will be conducted in a model configuration to examine how flow structures change with curvature, and numerical simulations will be performed to replicate this behaviour. These validated simulations will then be used to study the distribution of stationary and unsteady wall stresses in detail. In a more forward-looking aspect, with a view towards HIFU treatment of the stenosis, we will explore the potential impact of focused ultrasound streaming on flow modification and wall stresses.
