“…It is noted that the heat transfer rate rises in both the channel walls with varying values of time. Sasikumar et al [42] studied the impact of heat and mass transfer rate on MHD oscillatory flow in an asymmetric tapered channel. The study investigates various parameters that influence the flow and heat transfer characteristics.…”

The reviews in the literature reveal that nanofluids are more efficient for heat transfer than regular base fluids. The liquids that contain suspended nanoparticles have gained significant attention in recent years due to their potential enhancement of heat transfer in various applications including electronics cooling, power generation, and refrigeration. The present research work aims to examine the MHD radiative oscillatory nanofluid flow in a porous medium through an asymmetric wavy channel. The partial differential equations with physical boundary conditions represent the mathematical model of the flow problem. The governing equations are solved by the analytical method. H2O-Water and C2H6O2-ethylene glycol (EG) as base fluids are used with four different types of nanoparticles, namely gold (Au), copper (Cu), alumina (Al2O3), and silver (Ag). Graphs for velocity and temperature profiles are drawn for various shapes (cylindrical, brick, and platelet). Several plots illustrate the velocity, temperature, shear stress and heat transfer rate. Viscosity and thermal conductivity are evidently observed to be the most important physical quantities responsible for varying velocity and temperature profiles.

“…Recently, by Implementing Navier-Stokes equations in a cylindrical coordinate system and assuming axial symmetry under laminar flow conditions, Kafle et al [14] analyzed the blood flow through curved artery with mild stenosis. Also Sasikumar et al [15] discussed the heat and mass transfer effects on MHD Oscillatory flow of a couple stress fluid in an asymmetric tapered channel. In this paper, it is analyzed about the effects of heat and mass transfer effects on oscillatory flow of an incompressible electrically conducting viscous fluid under the influence of couple stress force in an asymmetric channel filled with porous medium.…”

MHD viscous oscillating type blood flow through lumen in arteries and varicose veins motivating to the study of blood flow in disordered blood vessels and veins. The blood flow in disordered nervous system, like varicose veins and other micro arteries in respiratory system is modeled geometrically in the shape of tapered curvy walls of varying cross section which is the new approach in this problem and the same has advantage compared to the other geometrical channel shapes. Blood taken as viscoelastic and optically thick fluid flowing through porous structure. Magnetic force considered in normal direction to the nervous system. Viscous dissipation and chemical reaction effects on blood flow are analyzed.

“…Concerning this aspect, several researchers [24][25][26][27] have premeditated the flow dynamics of hydromagnetic couple stress fluid by considering different boundary conditions in different channel configurations. Sasikumar et al [28] examined the oscillatory flow of a conducting couple stress fluid in a tapered channel with the impact of a magnetic field. Kumar et al [29] studied the MHD squeezing flow of a couple stress fluid with the presence of magnetite particles.…”

The present article deals with the analysis of the buoyancy-driven flow of a non-Newtonian couple stress fluid from an isothermal vertical plate under the influence of a spatially periodic magnetic field. We consider, in this work, the applied magnetic field to be a sinusoidal function of axial coordinate. We solve the coupled nonlinear governing equations numerically consistent with the help of an implicit Crank-Nicolson finite difference scheme. We analyse the impact of periodic magnetic field on the flow velocity of couple stress fluid and its eventual consequence on the convective transport of heat. The flow variables governing the underlying thermo-magneto-hydrodynamics are examined graphically in terms of velocity, temperature distribution, and friction-factor coefficients. The result indicates that the magnitude of the velocity and temperature increases for increasing the magnitude of the couple stress parameter, attributed primarily to the enhanced resistance due to larger degree collision of couple stress fluid particles. On the other hand, the local skin friction coefficient and heat transfer rate reduces owing to the adverse effect of the Lorentz force due to the applied magnetic field. RECEIVED
