Peristaltic Flow with Heat Transfer for Nano-Coupled Stress Fluid through Non-Darcy Porous Medium in the Presence of Magnetic Field

Abstract

In this paper, the peristaltic motion of nano-coupled stress fluid through non-Darcy porous medium is investigated, and the heat transfer is taken into account. The system is stressed by an external magnetic field. The Ohmic and viscous couple stress dissipations, heat generation and chemical reaction are considered. This motion is modulated mathematically by a system of non-linear partial differential equations, which describe the fluid velocity, temperature and nanoparticles’ concentration. These equations are transformed to non-dimensional form with the associated appropriate boundary conditions. The homotopy perturbation method is used to find the solutions of these equations as a function of the physical parameters of the problem. The effects of the parameters on the obtained solutions are discussed numerically and illustrated graphically. It is found that these parameters play an important role to control the solutions. Significant outcomes from graphical elucidation envisage that the inclusion of more magnetic field strength increases the resistance of the fluid motion. Intensification of the couple stress parameter attenuates the temperature values, while it increases with increasing thermophoresis parameter.

Peristaltic Transport of Carreau Coupled Stress Nanofluid with Cattaneo-Christov Heat Flux Model Inside a Symmetric Channel

“…Physically, this behavior occurs since elevating in the couple stress parameter leads to enhance the viscosity, which declines the fluid velocity. This important observation is consistent with the behavior recorded by [30], [33] and [45]. Also, velocity dwindles with an enhancement in 𝑀 𝐹 .…”

“…The findings are being utilized to examine non‐Newtonian and Newtonian fluids for various applications in electromagnetic peristaltic pumps and biomedical research. Emphasizing that the human body is made up of magnetic and electric fields, Abbas et al 14 examined the couple stress fluid transport while considering heat transfer and the magnetic field. While adjusting different parameters, their assessment of the graphical data derived from the numerical solution is explained.…”
