“…Extra deposition of fat inside the artery, constricts the arterial wall and directly affects the work function of the artery. The accumulation of substances in an artery is known as stenosis which changes hemodynamic conditions and flow patterns that were existing in the artery, early to catheterization [1], [2], [3]. This larger scale of coronary artery blockage causes heart attacks in the human body [4].…”

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.

In this paper, we study the impacts of variable viscosity , heat and mass transfer on magneto hydrodynamic (MHD) peristaltic flow in a asymmetric tapered inclined channel with porous medium . The viscosity is considered as a function of temperature. The slip conditions at the walls were taken into consideration. SmallReynolds number and the long wavelength approximations were used to simplify the governing equations. A comparison between the two velocities in cases of slip and no-slip was plotted. It was observed that the behavior of the velocity differed in the two applied models for some parameters. Mathematica software was used to estimate the exact solutions of temperature and concentration profiles. The resolution of the equations to the momentum was based on the perturbation method to find the axial velocity, pressure gradient and trapping phenomenon. The influences of the various flow parameters of the problem on these distributions were debated and proved graphically by figures.

“…If the strain rate is higher than 100 s-1, which happens in the large arteries, the blood behaves as a Newtonian fluid (constant viscosity). However, if the rate is lower than 100 s-1, the viscosity will present non-Newtonian behavior (variable viscosity) which occurs in the small arteries [14,15].…”

In recent years, Computational Fluid Dynamics (CFD) has been applied to biological systems for the study of physiological properties and the development of new medical devices. It has also been used for the hemodynamic evaluation of care in the diagnosis, treatment, and prevention of cardiovascular diseases. This article presents a brief analysis of the application of Computational Fluid Dynamics in hemodynamics in atherosclerosis, with a review of CFD in the study of blood flow, and in the medical area.
