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.

“…They found that fluid velocity increases in the Au blood model compared to TiO 2 and Cu blood model. Further, Sarwar and Hussain 20 investigated the effect of the gold nanoparticles shape on the stenosis artery and compared the results with Cu and Al 2 O 3 -nanoparticles. Bhatti and Abdelsalam 21 investigated the peristaltic flow with Tantalum (Ta) and Gold (Au) nanoparticles (NPs) in a symmetric channel under the influence of thermal radiation and magnetic field effect.…”
Present paper deals with the effect of Hall and ion slips on MHD blood flow through a catheterized multi-stenosis artery with thrombosis. Blood is considered a base fluid, and the suspension of Au and GO nanoparticles are used to form the hybrid nano-blood suspension. The hemodynamic mathematical model is presented to mimic the blood flow inside the artery subjected to Joule heating, thermal radiation, Hall and ion slip effects. The effect of the shape of nanoparticles and the variable viscosity depending upon hematocrit is taken into account. The mathematical model is presented in a curvilinear coordinate system, and a mild stenosis assumption is used to get the closed-form solutions. The reduced governing equations are solved using the Crank Nicholson scheme with “MATLAB.” The effect of various pertinent parameters on flow patterns are illustrated graphically. It is observed that increasing the Hall and ion slips parameter causes the increment in the fluid velocity due to an enhancement in the cyclotron frequency of the particles. The hybrid nanoparticles Au-GO/blood has a higher temperature profile than pure blood and unitary nanoparticles, as the thermal conductivity increases with an increase in nanoparticle concentration. Scientists and clinical researchers may find the present study useful in understanding the various illness’s conditions, including cancers, infections, and the removal of blood clots. Furthermore, current research may be helpful in the biomedical area, such as magnetic resonance angiography (MRA), which creates an image of an artery to identify any abnormalities in the artery. The current findings are consistent with recent findings in earlier blood flow research studies.
“…They computed the various results for wall shear stress, temperature, velocity, flow rate for particular height of stenosis. Many researchers 19 – 32 studied the applications of nanoparticles.…”
In this paper the behavior of flow of blood under stenosis suppositions is studied. Nanoparticles of Ag and Cu are being used with blood as base fluid. The problem governing equations are modeled into PDE’s, which are transformed into set of ODE’s with the help of useful similarity transformation. We investigated the solution numerically for various parameters on temperature and velocity distribution and shown in the form of tables and graphs. It is found that the velocity of blood increases while the temperature curve goes down by increasing the concentration of nanoparticles and also temperature curve decreases by increasing the values of gamma and Prandtl number. Furthermore, the calculated results shows that increment in flow parameter gamma caused an increase in velocity values. In the field of biomedicine, the important approach of nanotechnology is the use of nanoparticles in chemotherapy.
