The nanoparticles are frequently used in biomedical science for the treatment of diseases like cancer and these nanoparticles are injected in blood which is transported in the cardiovascular system on the principle of peristalsis. This study elaborates the effects of Lorentz force and joule heating on the peristaltic flow of copper and iron oxide suspended blood based nanofluid in a complex wavy non-uniform curved channel. The Brinkman model is utilized for the temperature dependent viscosity and thermal conductivity. The problem is formulated using the fundamental laws in terms of coupled partial differential equations which are simplified using the creeping flow phenomenon. The graphical results for velocity, temperature, streamlines, and axial pressure are simulated numerically. The concluded observations deduce that the solid volume fraction of nanoparticles reduces the velocity and enhance the pressure gradient and accumulation of trapping bolus in the upper half of the curved channel is noticed for temperature dependent viscosity.
这些纳米粒子经常被用于生物医学科学领域,用于治疗癌症等疾病,这些纳米粒子被注入血液中,血液在心血管系统中通过蠕动原理进行运输。本研究阐述了洛伦兹力和焦耳加热对铜和氧化铁悬浮在血液中的基于纳米流体的复杂波浪形非均匀弯曲通道中蠕动流的影响。Brinkman 模型用于依赖于温度的粘度和热导率。该问题是使用基本定律以耦合偏微分方程的形式提出的,并通过蠕动流现象进行简化。速度、温度、流线和轴向压力的图形结果是通过数值模拟得到的。得出的观察结果表明,纳米粒子的固相分数会降低速度,并增强压力梯度,并且在依赖于温度的粘度时,会注意到在上半部分弯曲通道中积累的捕获团块。
