Curved veins and arteries make up the human cardiovascular system, and the peristalsis process underlies the blood flowing in these ducts. The blood flow in the presence of hybrid nanoparticles through a tapered complex wavy curved channel is numerically investigated. The behavior of the blood is characterized by the Casson fluid model while the physical properties of iron (FeO) and copper (Cu) are used in the analysis. The fundamental laws of mass, momentum and energy give rise the system of nonlinear coupled partial differential equations which are normalized using the variables, and the resulting set of governing relations are simplified in view of a smaller Reynolds model approach. The numerical simulations are performed using the computational software Mathematica's built-in ND scheme. It is noted that the velocity of the blood is abated by the nanoparticles' concentration and assisted in the non-uniform channel core. Furthermore, the nanoparticles' volume fraction and the dimensionless curvature of the channel reduce the temperature profile.
弯曲的静脉和动脉构成了人体心血管系统,而蠕动过程是这些管道中血液流动的基础。对存在混合纳米颗粒时血液在锥形复杂波浪形弯曲通道中的流动进行了数值研究。血液的行为以Casson流体模型为特征,同时在分析中使用了铁(FeO)和铜(Cu)的物理性质。质量、动量和能量的基本定律产生了非线性耦合偏微分方程组,该方程组使用变量进行了归一化,并且鉴于较小的雷诺模型方法,对所得的一组控制关系进行了简化。使用计算软件Mathematica的内置ND方案进行了数值模拟。值得注意的是,纳米颗粒的浓度会降低血液的速度,并且在不均匀的通道核心中起到辅助作用。此外,纳米颗粒的体积分数和通道的无量纲曲率会降低温度分布。
