“…As a result, they concluded that the large Soret and Dufour number activates the temperature while reducing the concentration. In a further study conducted by Hayat et al, [8] on hyperbolic tangent nanofluid under similar conditions with MHD, it was noticed that temperature increases for higher Brownian movement and thermophoresis parameters. As of late Vaidya et al, [9] investigated the peristaltic motion of Rabinowitsch fluid in an inclined channel with compliant walls.…”

The current study emphasises a new approach to the peristaltic transport of Eyring-Powell fluid through a uniform channel. The study is done while considering the influence of variable liquid properties and wall properties through a uniform inclined channel, and the flow problem is developed mathematically. The study uses low Reynolds number and long-wavelength approximations to simulate no-slip conditions on the channel walls. The solutions are derived using a traditional double perturbation technique, and the nonlinear governing equations are normalized by employing pertinent non-dimensional factors. Graphical representations of the impact of significant physical parameters, such as velocity, temperature, concentration, and streamlines, are depicted and discussed. It was noted that Eyring-Powell fluid parameters and variable liquid properties have major impact during the peristalsis.

This study presents the exploration of unsteady magnetohydrodynamic (MHD) free convection flow of tangent hyperbolic nano-fluid flow on a moving cylinder with Brownian motion and thermophoresis effects. The current flow analysis yields nonlinear partial differential equations. The governing equations such as continuity, momentum, temperature and concentration are converted into dimensionless form and then solved numerically by adopting explicit finite difference method where Compaq Visual FORTRAN 6.6.a was also used for simulating the fluid flow system. The numerical outcomes are showed graphically to understand the result clearly. For the accurateness of the numerical technique a stability and convergence analysis was carried out. The aim was to illustrate the physical impacts of chemical reaction parameter, thermal radiation and viscous dissipation on various fluid fields along with the advanced visualization through streamlines. By comparing with the previous studies it was found that this fluid influenced the mass and heat properties more significantly rather than the other fluid. Additionally, this model predicts the shear thinning attitude significantly and describes the blood flow accurately. It has also applications in biological sciences, bio-engineering maneuver, and petroleum industries. Eventually the obtained outcomes were validated with previously published articles.

The aim of the present numerical investigation is to explore the impact of magnetic field on peristaltic flow of an incompressible tangent-hyperbolic fluid in an asymmetric channel. The present physical model is developed based on the considered flow configuration and with the help of small Reynolds number approximations. The current flow problem is revealed under the influence of applied magnetic field. The asymmetric channel has been considered to narrate the present physical problem. Considered physical situation in the current investigation gives the unsteady coupled highly nonlinear system of partial differential equations. Also, the simplified equations for pressure, pressure gradient, and streamlines have been obtained with the help of suitable transformations. A regular perturbation scheme is employed to produce the semi-analytical results of the present problem. The influence of various physical parameters on pressure, pressure gradient, and streamlines are illustrated with the help of graphs. From the present analysis, it is observed that the increasing magnetic number decreases the pressure and pressure gradient in the channel. Also, the size of trapping bolus increases with increasing values of Weissenberg number.

Peristaltic transport mechanism is very important in many industrial and real-life applications. For instance, blood flow in the heart, lungs and dialysis works on the principles of peristaltic process. Also, other mechanisms include the peristaltic flow examples, such as movement of urine to bladder through kidney, motion of chyme in intestinal path, spermatozoa motion, movement of food in esophagus, vasomotion of arterioles, capillaries, and venules, and many other biomedical applications. However, in realistic view, the process such as sanitary fluid movement, corrosive fluids transfer, motion of toxic fluids in various industries, plasma flow, blood flow, alloys and liquid metals flow, heavy oil lubrication with greases, and many others will fail to follow the Newtonian flow conditions. However, for these types of practical applications, it is quite obvious to choose the non-Newtonian fluid flow behavior to determine the transport properties. Further, various researchers have considered and studied the different non-Newtonian fluids based on their practical applications and flow complexity. The theoretical and experimental study of peristaltic fluid flow in a pump was studied by Latham. 1 It is clearly observed from Latham's study that the variations in the velocity profile were useful to describe how viscosity causes the peristaltic pump to work. Also, forward and backward flow occurs even though there is no pressure across the pump. Further, Latham's study was continued by Jaffrin and Shapiro 2 and they described the influ...
