Hydromagnetic peristaltic flow of Jeffrey nanofluid in a non-uniform wavy porous channel with Hall current and cross diffusion

The objective of this study is to analyze the effects of an aligned magnetic field and wall properties on the flow of a conducting Jeffrey nanofluid through a non-uniform, wavy porous channel. Additionally, the study considers the influence of Hall current, thermal radiation and the coupled Soret and Dufour effects on the flow dynamics. The nonlinear model equations of the problem are reduced to a system of non-dimensional partial differential equations. The exact solution for the velocity field is obtained. Furthermore, the perturbation technique is employed to obtain the temperature and fluid concentration fields. This study comprehensively investigates the effects of key parameters on the flow characteristics. The analysis is carried out through graphical representations and tabular data. The results indicate that a rise in the Darcy parameter leads to an increase in the velocity distribution. Elevated thermal radiation parameters and the Dufour number increase the fluid temperature.
