摘要

一种纳米血液模型被开发出来，用于研究在牛顿假设下注入金和银的血液通过多孔狭窄动脉的流动。考虑了壁面曲率、对流加热、壁面运动和粘性耗散。Darcy的模型模拟了多孔阻力，Tiwari-Das的模型捕捉到了纳米粒子的效应。通过相似变换对控制方程进行约简，并使用MATLAB的bvp4c求解器进行求解。提供了对现有研究的验证。结果表明，金血纳米流体的流速高于银血纳米流体。增加Biot数量可以增强动脉壁的冷却。详细的图表和3D等高线图说明了对温度、速度、表面摩擦和努塞尔数的影响。

Impact of gold and silver nanoparticles injected in blood with viscous dissipation.

A nano-blood model is developed to study the flow of gold- and silver-infused blood through a porous, stenotic artery under Newtonian assumptions. Wall curvature, convective heating, wall motion, and viscous dissipation are considered. Darcy's model simulates porous resistance, and the Tiwari-Das model captures nanoparticle effects. Governing equations are reduced via similarity transformations and solved using MATLAB's bvp4c solver. Validation against existing studies is provided. Results show gold-blood nanofluid achieves higher velocities than silver-blood. Increasing the Biot number enhances cooling at the arterial wall. Detailed graphs and 3D contour plots illustrate the effects on temperature, velocity, skin friction, and Nusselt number.
