论文摘要
通过狭窄和动脉瘤刚性动脉的血流和血流动力学特性的数值预测在狭窄区域存在血凝块的情况下进行了研究。有限元方法已用于在二维笛卡尔坐标系统中求解连续性，动量，Oldroyd-B和生物热传输的稳定偏微分方程。目前的研究具有计算血液速度，压力和阻力系数的潜力，具有狭窄和Aneurysm的喉咙上具有重大意义。这些模型还用于研究所有修饰的模拟，血凝块和血液动力学特征的影响。该模型的狭窄和动脉瘤区域发现了后流和再循环区域。定量分析是通过具有血流血流动力学因子的生理意义的数值计算来完成的，这取决于显示目前模型的有效性的无量纲参数。
Numerical predictions of blood flow and hemodynamic properties through a stenotic and aneurysmal rigid artery are studied in the presence of blood clot at constricted area. Finite element method has been used to solve the steady partial differential equations of continuity, momentum, Oldroyd-B and bioheat transport in two dimensional cartesian coordinates system.The present investigation carries the potential to compute blood velocity, pressure and drag coefficient with major significance at the throat of stenosis and aneurysm. The models are also employed to study of simulation, influence of blood clot and hemodynamical characteristics for all modifications. The back flow and recirculation zones are found at stenotic and aneurysmal region for the model. The quantitative analysis is completed by numerical calculation having physiological significance of hemodynamical factors of blood flow depends on the dimensionless parameters which show the validity of present model.
