There are many different mathematical models and solution techniques dealing with the blood flows. A twophase (liquid-solid) model solved by a perturbation method will be introduced. Effects of hematocrit, Reynolds number, area reduction, and different geometries of the stenotic channel are studied on the velocity, pressure gradient, and streamlines. The flow characteristics (velocity and pressure) give a great increase as the stenosis classified as a sever stenosis. It is found that, the stenosis geometry has a great effect on the pressure gradient in the axial direction, and also there is a change in velocity profile in each cross section of the geometry. The hematocrit has a noticed effect on the flow velocity and pressure gradient, in which as the hematocrit increases the maximum velocity decreases before the throat while it increased after that section.

“…Sadaf and Abdelsalam [22] revealed the hostile effect of nanofluid in a wavy nonuniform annulus with flexible boundaries. Some other worthy research studies by Abdelsalam and Bhatti [23], Abdelsalam and Bhatti [24], Abdelsalam and Bhatti [25], and Eldesoky et al [26] have been performed with magnetic field effect in a tube for blood flow. Biological organs in which biofluids flow have a small degree of roughness or uncertain (random) spatial variability.…”

A mathematical study for investigating heat transfer for the peristaltic flow of a Newtonian fluid through a nonuniform inclined channel while considering surface roughness of the inner wall has been conducted. Special attention is focused to analyze the physical behaviour of various flow characteristics at different magnitudes of surface roughness parameter. The results obtained for temperature have been characterized by two boundary conditions: uniform surface temperature and uniform heat flux. Effect of inner wall surface roughness and angle of inclination on the heat transfer for the peristaltic flow through a nonuniform channel has been discussed in detail. The expression for pressure gradient, velocity, and the temperature was obtained. The effect of inner wall surface roughness and the angle of inclination, on pressure rise and temperature, has also been elaborated in detail. The problem formulation developed has been solved using the long wavelength and low Reynolds number assumption.

“…Various types of annular pathways have become important geometries for uid transfer devices since they have numerous applications in engineering. [9][10][11] Also, uid ows with heat transfer taking place in gaps, such as between two concentric cylinders (annuli), for pure and hybrid nanouids have become technically more important. Therefore, signicant work has been done for circular annuli using nanouids.…”
