“…Figure 6 shows the variation in the wall shear stress and it is observed that the wall shear stress decreases with increasing the magnetic parameter as reported in [24]. Figure 7 shows that wall shear stress decreases maximum at the throat of stenosis by increasing the values of the slip parameter h as noticed in [24,25,26,29]. Figure 8 shows that the effective viscosity and wall shear stress slightly decrease with body acceleration.…”

In this analysis, we present a theoretical study to examine the combined effect of both slip velocity and periodic body acceleration on an unsteady generalized non-Newtonian blood flow through a stenosed artery with permeable wall. A constant transverse magnetic field is applied on the peristaltic flow of blood, treating it as an elastico-viscous, electrically conducting and incompressible fluid. Appropriate transformation methods are adopted to solve the unsteady non-Newtonian axially symmetric momentum equation in the cylindrical polar coordinate system with suitably prescribed conditions. To validate the applicability of the proposed analysis, analytical expressions for the axial velocity, fluid acceleration, wall shear stress and volumetric flow rate are computed and for having an adequate insight to blood flow behavior through a stenosed artery, graphs have been plotted with varying values of flow variables, to analyse the influence of the axial velocity, wall shear stress and volumetric flow rate of streaming blood.

The present analysis focuses on the thermal radiation and slips effects on the peristaltic movement of Sisko fluid with the symmetric compliant channel with rheological properties, enhancing damping tools, protection apparatus individuals and in various distinct mechanical procedures. Keeping in mind the considered problem assumptions (Non-Newtonian Sisko fluid model, power-law model, Prandtl number, wall properties, porous space, etc) it is found that the modeled equations are coupled and non-linear. Using low Reynold's number and long wavelength assumptions, the governing system of a nonlinear coupled system of equations with appropriate boundary constraints is solved with the perturbation technique. Due to convectively heated surface fluid between the walls having a small temperature. Sherwood and Nusselt numbers both deduce for fixed radiation values and different Sisko fluid model quantity. Skin friction is maximum in the case of Newtonian, while minimum in case of dilatant model and pseudoplastic models. The influence of numerous parameters associated with flow problems such as Hartman number, Prandtl number, and slip parameters are also explored in detail and plotted for concentration profile, thermal distribution, and momentum distribution profile. From this analysis, it is concluded that velocity escalates for the larger slip. Also, skin friction is found similar for Newtonian and pseudoplastic models where in case of dilatant model it is little different but it increases for these three cases when Schmidt number is increased. Moreover, the shearthinning and shear-thickening behavior of the fluid model is also explained in detail. Industrial applications of the Sisko model include minimum friction , reduction in oil-pipeline friction, uses as a surfactant for comprehensive scales cooling and heating systems, scale-up, flow tracers, and in several others.

In this paper, the mixed convective flow of an electrically conducting, viscous incompressible couple stress fluid through a vertical channel filled with a saturated porous medium has been investigated. The fluid is assumed to be driven by both buoyancy force and oscillatory pressure gradient parallel to the channel plates. A uniform magnetic field of strength B0 is imposed transverse to the channel boundaries. The temperature of the right channel plate is assumed to vary periodically, and the temperature difference between the plates is high enough to induce radiative heat transfer. Under these assumptions, the equations governing the two-dimensional couple stress fluid flow are formulated and exact solutions of the velocity and the temperature fields are obtained. The effects of radiation, Hall current, porous medium permeability and other various flow parameters on the flow and heat transfer are presented graphically and discussed extensively.
