对动脉内血流的模拟和数值模拟的贡献
Contribution a la modelisation et simulation numerique de l ecoulement du sang dans l artere
摘要：
医学介入技术对动脉分区的病理（动脉瘤、夹层、缩窄、动脉粥样硬化）的控制提出了许多问题，为此，我们对医学影像所拍摄的肾动脉中的血流进行了建模和数值模拟。从血管造影、血管扫描仪和内窥镜的医学图像中重建几何形状。同时考虑到血液像牛顿流体一样平稳流动。得到的结果在物理参数方面的速度，动态压力示出，最简单的情况下，足以收集相关数据的发展狭窄或血栓形成的动脉。
英文摘要：
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.
