In this paper, we have discussed the influence of copper nanoparticles on a blood flow through composite stenosed artery with permeable walls. The nature of blood is discussed mathematically by considering it as viscous nanofluid. The study is carried out for a blood vessel under mild stenosis approximations and expressions of the temperature, velocity, resistance impedance to flow, wall shear stress and the pressure gradient is obtained by using corresponding boundary conditions. Results for the effects of permeability on blood flow through composite stenosis have been discussed graphically. The considered analysis also summarizes that the drug copper nanoparticles are efficient to reduce hemodynamics of stenosis and could be helpful to predict important uses for biomedical applications. Results indicate that nanoparticles are helpful as drug carriers to minimize the effects of resistance impedance to blood flow or coagulation factors due to stenosis.
在本文中,我们讨论了铜纳米颗粒对血液流经具有可渗透壁的复合狭窄动脉的影响。通过将血液视为粘性纳米流体,从数学角度讨论了血液的性质。该研究是在轻度狭窄近似条件下对血管进行的,并通过使用相应的边界条件获得了温度、速度、流动阻力阻抗、壁面剪应力和压力梯度的表达式。通过图形讨论了渗透率对血液流经复合狭窄的影响结果。所考虑的分析还总结出,药物铜纳米颗粒在降低狭窄的血液动力学方面是有效的,并且有助于预测其在生物医学应用中的重要用途。结果表明,纳米颗粒作为药物载体有助于最小化由于狭窄导致的血流阻力阻抗或凝血因子的影响。
