The current investigation was based on a simulation employing CFD in COMSOL Multiphysics. The base fluid that was used in this simulation was blood. The flow was considered as a laminar, unsteady and incompressible Newtonian fluid, and the Newtonian nature of blood is acceptable at high shear rate. The behavior of blood flow was analyzed with the objective of obtaining pressure, temperature and velocity effects through an arterial stenosis. Two types of nanoparticles were used in this work: silver (Ag) and gold (Au). The equations of mass, momentum and energy were solved by utilizing the CFD technique. A fine element size mesh was generated through COMSOL. The results of this analysis show that velocity changes through confined parts of the artery, the velocity in a diseased region is higher and the velocity decreases before and after the stenotic region. In the heat transfer feature, the upper and lower boundary temperature was set to 24.85 °C and 27.35 °C, respectively. The nanoparticles affected the physical properties of blood, such as thermal conductivity, density, dynamic viscosity and specific heat. The addition of gold and silver nanoparticles prevented overheating because both nanoparticles have a high thermal conductivity, which has a principal role in dissipating temperature quickly. Nusselt number variations were also calculated and the results show that the curve decreases inside the stenosis. It could be concluded that the streamlines show abnormal behavior and recirculation occurs just after the stenosed area at t = 0.7 s and 1 s. These results will help greatly in the treatment of stenosed arteries.

“…The flow of the blood through an artery having multiple stenoses of both symmetric and non-symmetric shapes is studied by Zidan et al [36]. Several theoretical studies were also conducted to discuss the flow motions driven by combined electroosmosis and peristaltic pumping [2,5,6,17,21,22,27].…”

This analysis is conducted for a theoretical examination of the fluid flow characteristics and heat transferred by the nanoparticle-enhanced drilling muds flowing through drilling pipes under various physical conditions. Here, an important type of drilling fluid called Aphron drilling fluid is under consideration which is very effective for drilling in depleted regions. The rheological characteristics of the drilling fluid are predicted by Herschel-Bulkley fluid model. The fluid flow is driven by peristaltic pumping which is further aided by electroosmosis. The zinc oxide nanoparticles are dispersed in the aphron drilling fluid to prepare the nanofluid. The administering set of equations are simplified under the lubrication approach and the closed-form solutions are obtained for velocity and pressure gradient force. However, numerical solutions are executed for the temperature of nanofluid through built-in routine bvp4c of MATLAB. Fluid flow characteristics are analyzed for variation in physical conditions through graphical results. The outcomes of this study reveal that velocity profile substantially rises for application of forwarding electric field and temperature profile significantly decays in this case. An increment in temperature difference raises the magnitude of the Nusselt number. Furthermore, the nanoparticle volume fraction contributes to fluid acceleration and thermal conductivity of the drilling fluid.

“…Further study about the blood flow in an artery having multiple stenoses is done by authors. [37][38][39][40] Literature shows that graphene oxide and titanium dioxide exhibit unique sets of material properties. To the authors' best knowledge, no work is performed to evaluate the impact of resistive and radiative heats on the GO and TiO 2 suspended Sutterby blood flow through the stenosed artery in the existence of the Darcy-Forchheimer, heat convection, and hydromagnetic conditions.…”

The antibacterial properties of graphene oxide and the anti-cancer effects of TiO2particles play a vital role in the drug delivery system. Mixing these nanoparticles in the blood by considering the complex rheological natured Sutterby model can maximize drug delivery results. A theoretical analysis is made to evaluate the impact of resistive and radiative heat on the graphene oxide (GO), and titanium dioxide (TiO2) suspended Sutterby blood flow through the stenosed artery. A mathematical model is developed and resolved numerically using the Keller-box approach. The Darcy–Forchheimer, heat convection, and hydromagnetic conditions are considered for physical relevance. The outcomes are obtained for nano and hybrid nano cases and explored with tabular and pictorial representations. It is found that the addition of the GO nanoparticles to the blood-TiO2 combination boosts the heat transmission without affecting the wall friction. This minimizes the external pressure on the blood flow.
