Contribution a la modelisation et simulation numerique de l ecoulement du sang dans l artere

TL;DR

This paper presents a numerical modeling and simulation of blood flow in the renal artery, reconstructed from medical images, to aid in understanding arterial pathologies like stenosis and thrombosis.

Contribution

It introduces a method for reconstructing arterial geometry from medical imaging and simulating blood flow assuming Newtonian fluid and stationary conditions.

Findings

Relevant data on velocity and pressure for arterial pathologies

Simplified model effectively predicts stenosis and thrombosis

Simulation results align with physical expectations

Abstract

Numerous are the questionings raised by medicine interventionnelle, concerning the hold in charge of the pathologies of the arterial partition (aneurysm, dissection, coarctation, atherosclerosis).for it we made the modeling and the numeric simulation of the blood flow in the renal artery taken by the Medical imagery. Geometry has been rebuilt from the medical pictures of angiography, angioscanner and IRM. While considering that blood like a fluid Newtonian and stationary flow. The results gotten in terms of the physical parameters as the velocity, the dynamic pressure is shown that the simplest case was enough to collect relevant data for the development of stenos or thrombosis in the arteries.
