The blood flow through stenotic artery is one of the important research area in computational fluid mechanics due to its application in biomedicine. Aim of this research work is to investigate the impact of nanoparticles on the characteristics of human blood flow in a stenosed blood artery. In under consideration problem Newtonian fluid is assumed as human blood. Newtonian fluid flows through large blood vessels (more than 300 μm). The constitutive equations together with the boundary conditions are diminished to non-dimensional form by using boundary layer approximation and similarity transfiguration to attain the solution of velocity and temperature distribution of blood flow through arterial stenosis numerically with the help of Matlab bvp4c. The results for physical quantities at cylindrical surface are calculated and their effects are also presented through tables. The heat transfer rate increases throughout the stenosed artery with the concentration of copper nanoparticle. Velocity curve decreases by increasing the values of flow parameter and nanoparticle volume fraction. Temperature curve increases due to increase in the values of nanoparticle volume fraction and decrease in Prandtl number.
由于在生物医学中的应用,狭窄动脉中的血流是计算流体力学术语中的一个重要研究领域。本研究工作的目的是研究纳米粒子对狭窄动脉中人体血液流动特性的影响。在所考虑的问题中,牛顿流体被假设为人体血液。牛顿流体流经大血管(大于 300μm)。通过边界层近似和相似变换,将本构方程和边界条件无量纲化,以 Matlab bvp4c 数值求解动脉狭窄处血流的速度和温度分布。计算了圆柱面上的物理量值,并通过表格展示了它们的影响。随着铜纳米粒子浓度的增加,整个狭窄动脉的传热率增加。随着流动参数和纳米粒子体积分数的增加,速度曲线减小。由于纳米粒子体积分数的增加和普朗特数的减小,温度曲线增加。
