Title Effects of Porous Rotating Frame on Peristaltic MHD Jeffrey Fluid Flow

Author(s) Ayesha Akhtar

Abstract This study focuses on the peristaltic transport of a Jeffrey fluid within a porous rotating frame under the influence of magnetohydrodynamics (MHD). The Jeffrey fluid model, which accounts for relaxation and retardation times is considered to better describe the viscoelastic characteristics of biological and industrial fluids. The governing equations describing the system are non-linear and non-homogeneous partial differential equations formulated in Cartesian coordinates. By applying the lubrication approximation, assuming a low Reynolds number and long wavelength, the momentum equations are simplified and solved using the perturbation method. Analytical solutions are obtained and further examined through symbolic computation using Mathematica. The novelty of this research lies in addressing the unexplored effects of rotation on Jeffrey fluid peristaltic flow in a porous medium under MHD conditions, an area that has received limited attention in the literature. The study investigates how the velocity distribution and streamline patterns are influenced by variations in rotational and magnetic parameters. The outcomes are expected to provide deeper insights into the behavior of non-Newtonian fluids in rotating porous environments, with potential applications in biomedical devices, polymer processing, and peristaltic pumping technologies widely used in industry.
