Peristaltic transport of non-Newtonian nanofluid through an asymmetric microchannel with electroosmosis and thermal radiation effects

In this paper, we have investigated the electroosmotic-driven flow of Sutterby nanofluid under the peristaltic mechanism with the influence of a magnetic field. The flow of fluid is taken into the undulating asymmetrical microchannel. Using Debye-Huckel linearization approximation, the fluid velocity and temperature profiles were calculated. The nanofluid flow is considered in the static electric field on the horizontal side and the applied external magnetic field in the transversal direction. The flow pattern also considers thermal radiation and the Joule heating parameter. Governing fluid flow equations such as continuity, momentum and temperature equations are reduced in consideration of the long wavelength and the very tiny Reynolds number approximation. The resulting nonlinear equations are resolved numerically with the help of the built-in NDSolve function made available in the computational mathematical software MATHEMATICA. Graphical illustrations of the fluid velocity profile, temperature and Trapping phenomenon (Streamlines) have been explained in detail. It is found that increasing the values of Hartmann number velocity of the nanofluid diminishes, and the temperature of the fluid enhances. Results from the Sutterby nanofluid model might have a broad range of applications, such as cancer tissue destruction, disease diagnosis, etc.
