On Elastic Arterial Blood Flow Systems

Abstract: In this lecture we first review modeling and simulation that have been carried out recently for steady and unsteady two-phase arterial blood flow systems with stenosis based on the experimentally generated data but with focus on blood pressure and flow inside the arteries. Next, we consider the relevant governing equations for the motion of the surface of the elastic and deformable arteries and in the presence of stenosis. We determine solutions for the displacement components of the elastic wall motion of the artery system and present the results for the effects of elastic stresses, hematocrits, wall stiffness, wall thickness, volume flow rate, blood pressure and other forces on the artery system. We explain several notable effects such as those by the elastic artery surface on the blood pressure and flow in the stenosis zone, etc., and how such effects can modify the patience’s health.

Brief Biography of the Speaker: Daniel N. Riahi is Professor Emeritus in the Dept of Mechanical Science and Engineering at The University of Illinois at Urbana-Champaign (UIUC) and as Professor in the School of Mathematical & Statistical Sciences at The University of Texas Rio Grande Valley (UTRGV). Dr. Riahi’s research work & interest include studies in convection, shear flow , hydrodynamic stability, flow during solidification & crystal growth, electrospinning and forcespinning processes, and math modeling and computation with applications in engineering, mechanical, biomedical & physical sciences. His research accomplishments include new theories and a number of discoveries in fundamental areas in above subjects, some of which were already confirmed by the experimental studies.
