The study of (Cu, TiO2, Al2O3) nanoparticles as antimicrobials of blood flow through diseased arteries

The current investigation is the study of different types of nanoparticles such as copper (Cu), titanium (TiO2) and aluminum (Al2O3) in the existence of mild stenosis lesions. To account the gravitational effects artery is considered longways. The exact solutions are achieved by using the Euler-Cauchy method. The presented graphs show the thermophysical properties of fluids (blood) and nanoparticles through the velocity profile (Vz), volume fraction (ϕ), Grashof number (Gr), heat source or sink parameter (β), resistance impedance (λ), wall shear stress(τrz) and temperature profile (θ). The obtained results show that the transmission of axial velocity curves through a pure fluid (ϕ = 0) is substantially lower at (-0.505 ≤ r ≤ 0.505) than that through a nanofluid. The size of trapping bolus in the case of pure fluid flow (ϕ = 0) is smaller than that through nanofluid.
