“…So as the value of the applied magnetic field parameter increases, Lorentz force which stabilizes between moving magnetic particles and the applied magnetic field opposes the motion of the blood flow and causes reduced velocity profile of the blood flow. The result for the velocity profile agrees well with the result reported by Sharma et al [33]. The effect of the magnetic field parameter (M) on temperature profile is displayed in Fig.6.…”

In this paper, we present the mathematical study of heat and mass transfer effects on an arterial blood flow under the influence of an applied magnetic field with chemical reaction. A case of mild stenosis is considered in a non-tapered artery which is inclined at an angle γ from the axis. The variable viscosity of the blood is considered varying with the hematocrit ratio. Governing non-linear differential equations have been solved by using an analytical scheme, homotopy perturbation method to obtain the solution for the velocity, temperature and concentration profiles of the blood flow. For having an adequate insight to blood flow behavior through a stenosed artery, graphs have been plotted for wall shear stress, velocity, temperature and concentration profiles with varying values of the applied magnetic field, chemical reaction parameter and porosity parameter. The results show that in an inclined artery, the magnitude of the wall shear stress at stenosis throat increases as values of the applied magnetic field increase while it reduces as the values of both the chemical reaction and porosity parameters increase. Contour plots have been plotted to show the variations of the velocity profile of blood flow as the values of the height of the stenosis as well as the influence of the applied magnetic field increase.

“…Most of these studies were investigated in the absence of heat or heat and mass transfer, see for example the work of Fetecau et al [ 12 – 14 ], Jamil and Fetecau [ 15 ], Rubab et al [ 16 ] and Abdulhameed et al [ 17 ]. Such problems have also applications in biomagnetic fluid dynamics, see for example Sharma et al [ 18 ], and Nehad et al [ 19 ], where they used cylindrical coordinates and investigated the blood flow in cylindrical shaped arteries. Khan et al [ 20 – 22 ], used cylindrical coordinates and investigated heat or heat and mass transfer in converging and diverging channels.…”

This paper studies the heat transfer analysis caused due to free convection in a vertically oscillating cylinder. Exact solutions are determined by applying the Laplace and finite Hankel transforms. Expressions for temperature distribution and velocity field corresponding to cosine and sine oscillations are obtained. The solutions that have been obtained for velocity are presented in the forms of transient and post-transient solutions. Moreover, these solutions satisfy both the governing differential equation and all imposed initial and boundary conditions. Numerical computations and graphical illustrations are used in order to study the effects of Prandtl and Grashof numbers on velocity and temperature for various times. The transient solutions for both cosine and sine oscillations are also computed in tables. It is found that, the transient solutions are of considerable interest up to the times t = 15 for cosine oscillations and t = 1.75 for sine oscillations. After these moments, the transient solutions can be neglected and, the fluid moves according with the post-transient solutions.

“…The obtained results show that the velocity of the blood as well as that of the magnetic particles decreases by increasing the magnetic field. This same approach has been used experimentally by Sharma and al. (2015) to measure the velocity of artificial blood with different magnetic fields intensities.…”

The objective of the present study is the active flow control of blood in the aorta with atherosclerosis using an External Magnetic Field (EMF) in order to facilitate the blood flow. For that purpose, a numerical investigation has been developed with a Magneto-hydrodynamics flow modelisation. The blood is considered homogeneous, incompressible and Newtonian and the fluid flow is assumed to be unsteady, two-dimensional and laminar. The aorta tissue is electrically conductive. Fluent software has been used to solve the governing equations. The results relating to velocity, pressure and the wall shear stress indicate that the presence of the EMF considerably influences the blood flow. The flow control deals with the effects of the EMF direction of application and its intensity. The results show that by applying an EMF, the blood velocity and pressure in the aorta are entirely affected. The direction and the intensity of the EMF allow minimization of the flow instabilities due to the geometrical singularities. Therefore, applying an EMF can be considered an appropriate method for flow control in order to obtain a uniform blood circulation around the atherosclerosis.
