Numerical exploration of the peristaltic flow of MHD Jeffrey nanofluid through a non-uniform porous channel with Arrhenius activation energy

Abstract

This article describes the peristaltic flow of a Jeffrey nanofluid through a vertical divergent channel subject to the impacts of thermal radiation, heat generation, activation energy, and an angled magnetic field. Coupled governing non-linear differential equations are obtained by approximating the system with the lubrication approximation. Further, distributions of the velocity, temperature, concentration, heat, and mass transfer rates at the channel wall are all calculated numerically. In addition, the consequences of pertinent physical parameters on the flow quantities are analyzed via tabular and graphical illustrations. It is noted that the velocity distribution exhibits an increasing behavior for thermal and solute Grashof numbers. Augmentation in axial velocity is noticed by escalating the values of the Hall current parameter. For greater values of the activation energy parameter, the concentration and mass transfer rate were elevated. The present study has a wide range of applications in biomedical engineering and environmental engineering.
