Peristaltic propulsion of Ree-Eyring nanofluids: investigations on the role of magnetic field and variable thermophysical properties

This study delves into the intricacies of the peristaltic mechanism exhibited by a non-Newtonian Ree-Eyring Nano-liquid, investigating its behavior in the presence of varying liquid properties and heat and mass transfer phenomena. The objective of the present investigation is to conduct a thorough analysis of this mechanism, taking into account the influence of wall properties and the dynamic nature of liquid properties. The Buongiorno nanofluid model is adopted to investigate heat and mass transfer phenomena, while the Ree-Eyring non-Newtonian fluid model is employed to comprehend the complex rheological characteristics of the fluid. This complex process’s modeling involves utilizing long wavelengths and low Reynolds number approximations. The resulting non-linear ordinary differential equations are addressed using the homotopy perturbation technique, incorporating appropriate non-dimensional parameters. A strong correlation is observed between homotopy perturbation results and previously existing literature. The magnetic field is a critical factor in shaping the fluid flow behavior, while the interplay between variable liquid properties and nanofluid characteristics significantly affects temperature profiles. The Ree-Eyring fluid and magnetic parameters enhance the heat and mass transfer coefficient. This research advances the understanding of peristalsis in the context of Ree-Eyring Nano-liquids, holding promising implications for diverse applications in both technical and medical domains.
