In this research, the electro-osmotic effects are highlighted for a blood-based hybrid nanofluid flow across an artery infected with multiple stenosis. The artery has permeable walls together with slip boundary effects. The slip and permeable boundary conditions model the more realistic blood flow problems. The governing equations of the problem are converted into non-dimensional form by introducing adequate dimensionless variables and acquired the exact solutions. The detailed study of heat transfer is given by Joule heating and viscous dissipation effects. The disorder of fluid flow is investigated by the mathematical study of entropy generation. Analytically attained solutions are examined graphically for both symmetric and non-symmetric shapes of stenosis. Streamlines are analyzed for varying values of flow rate Q and electro-osmotic parameter m. The flow velocity has smallest values on the axis of channel and gets higher value near the boundary walls. The temperature profile delineates opposite behavior to the velocity, and it is parabolic in nature. The velocity reduces towards the non-uniform stenosis except for electroosmotic parameter m. The temperature has larger magnitude in the case of anti-symmetric stenosis. Moreover, the stability of velocity solution is also analyzed.

The surgical intercede firstly requires the spotting and quantification of stenosis. The analysis of blood flow in such arteries lead to the prediction of hemodynamics mechanism in these diseased arteries. It is further helpful in designing the devices that imitates the blood flow and in diagnostic tools formation. The hemodynamics mechanism of a curved artery having multiple stenosis is interpreted. An exact as well as a numerical solution approach is utilized in the present analysis. Since blood flow is usually turbulent in such stenosed arteries and the advantage of using numerical approach is that we have also considered the turbulent flow phenomena in this curved artery. Exact solutions provide the line graphs for this flow problem while the numerical simulations are obtained by using the free source OPENFOAM software. The numerical approach is more convenient to consider the desirable location of stenosis. It means that we can construct various complex geometries with multiple locations of stenosis more conveniently by using the numerical approach.

“…In another study, Reddy et al [11] reported the influence of viscosity on Jeffrey fluid peristaltic flow in a uniform tube. Kadhim et al [12] studied whether the blood flow in the arterial area was within the range of possible non-Newtonian rheological qualities in the presence of various twofold stenosis in the left coronary artery. In another study, Hayat et al [13] explored the peristaltic flow in a tube with an endoscope.…”

Computational fluid dynamics is a computer simulation technique used to study the effects of stenosis and aneurysm degree on haemodynamics in the blood vessels such as blood velocity, pressure, and wall shear stress. The current study employed the numerical simulations of pulsed blood flow using the Carreau non-Newtonian rheological and Newtonian models to model the wall shear stresses and haemodynamics in blood vessels. Furthermore, the model included three stenosis areas with different diameters, 70%, 80%, and 90%, and two aneurysm areas with different diameters, 15% and 44%. The study observed the blood velocity, pressure, and wall shear stresses at the damaged blood vessels areas. It was found that the maximum velocity was observed from stenosis when the stenosis ratio was increased to 90%. Additionally, the velocity increased up to 3.4 times, which led to increased blood shear stresses to up to 8.4 times, when the start acceleration flow and peck flow were compared. It is known that the degree of damage on blood vessels produces the most significant influence on local blood pressure and shear stresses. Therefore, it was concluded that stenosis at 90% may probably lead to serious lesions and effectively block the bloodstream by the ensuing thrombus.
