“…Their studies show that an increase in variable viscosity parameters accelerates the flow hence bolus size increases. Pulsatile flow analysis has gained a lot of attention because of its applications in respiratory system, circulatory systems, microelectromechanical system, reciprocal pumps, vascular diseases, and internal combustion engines 21 – 25 . Malathy and Srinivas 26 used perturbation method to investigate the MHD pulsating flow between two permeable beds.…”

Fluid–structure interaction (FSI) gained a huge attention of scientists and researchers due to its applications in biomedical and mechanical engineering. One of the most important applications of FSI is to study the elastic wall behavior of stenotic arteries. Blood is the suspension of various cells characterized by shear thinning, yield stress, and viscoelastic qualities that can be assessed by using non-Newtonian models. In this study we explored non-Newtonian, incompressible Casson fluid flow in a bifurcated artery with a stenosis. The two-dimensional Casson model is used to study the hemodynamics of the flow. The walls of the artery are supposed to be elastic and the stenosis region is constructed in both walls. Suitable scales are used to transform the nonlinear differential equations into a dimensionless form. The problem is formulated and discretized using Arbitrary Lagrangian–Eulerian (ALE) approach. The finite element method (FEM) technique is used to solve the system of equations, together with appropriate boundary conditions. The analysis is carried out for the Bingham number, Hartmann number, and Reynolds number. The graphical results of pressure field, velocity profile, and load on the walls are assessed and used to study the influence of hemodynamic effects on stenotic arteries, bifurcation region, and elastic walls. This study shows that there is an increase in wall shear stresses (WSS) with increasing values of Bingham number and Hartmann number. Also, for different values of the Bingham number, the load on the upper wall is computed against the Hartmann number. The result indicate that load at the walls increases as the values of Bingham number and Hartmann number increase.

“…Nowadays, the analysis of pulsating flow in a pipe/channel is very important because of a wide variety of applications in engineering, science and industries. For example, transpiration cooling, reciprocating engines, pulsed heat exchanger and refrigerating devices for gas turbine engines, blood dialysis in artificial kidneys, bio-fluid networks and heat dissipation in electronics, thermo - hydraulic studies, and so on 24–30 . Rajamani and Reddy 31 investigated the MHD pulsating flow of couple stress nanofluid with Joule heating and viscous dissipation impacts in a channel by using perturbation method.…”

The current exploration deals with the third grade hydromagnetic pulsating flow of blood-gold nanofluid in a channel with the presence of Ohmic heating, viscous dissipation and radiative heat. In the present analysis, blood (base fluid) is considered as third-grade fluid and gold (Au) as nanoparticle. This investigation is useful in the fields of food processing system, pressure surges (pulsatile flow application), biomedical engineering, nano drug delivery, radiotherapy, and cancer therapeutic (nanofluid application). Perturbation method is employed to transform the set of governing partial differential equations (PDEs) into the ordinary differential equations (ODEs) and then solved by employing the fourth order Runge-Kutta method with the aid of the shooting technique. The impacts of emerging dimensionless parameters of velocity, temperature, and heat transfer rate of blood-Au nanofluid are analysed via pictorial outcomes in detail. The obtained results depict that the improvement in viscous dissipation and heat source enhanced the temperature of third grade nanofluid. The velocity and temperature of the nanofluid are declining functions with the enhancement of frequency parameter, material parameter, and non-Newtonian parameter respectively. Intensifying the volume fraction of nanoparticle dwindles the velocity and temperature of nanofluid. Enhancing volume fraction and viscous dissipation accelerates the heat transfer rate of nanofluid. The velocity, temperature, and heat transfer rates are decreased by an escalation of the Hartmann number. Further, enhancing the radiation parameter reduces the heat transfer rate and temperature of nanofluid.

“…The study of the pulsatile flow of Newtonian or non-Newtonian fluids in a channel/pipe is important to explore many natural operations, especially in the biological systems, for example, biological membranes, human blood and complex fluids [1][2][3][4][5][6][7] which are subject to the oscillations in pressure gradient. Kim et al 8 studied the problem of pulsating flow and heat transfer in a channel filled with a porous medium.…”

The present work discloses the magnetohydrodynamic pulsating flow of blood-carrying nanoparticles in a channel with the viscous dissipation and Joule heating effects. Couple stress fluid is treated as blood which is the base fluid. The Maxwell Garnett model for thermal conductivity of nanofluid is considered. The thermal radiation and heat source/sink impacts are taken into account. Analytical expressions for dimensionless flow variables are obtained by employing the perturbation method. The impact of active parameters on flow variables is graphically presented. The obtained results show that the velocity of nanofluid increases with an increment in frequency parameter, whereas it decreases for a rise in Hartmann number, nanoparticles volume fraction and couple stress parameter. There is an enhancement in temperature of nanofluid with increasing viscous dissipation, whereas there is a decrease in temperature with an increase in the applied magnetic field. The Nusselt number rises with an enhancement in volume fraction of nanoparticles and Hartmann number at both the walls. Further, the validity of present results is assured by the comparison of analytical and numerical outcomes with an excellent harmony.
