Mixed convection and thermal radiation effect on MHD peristaltic motion of Powell-Eyring nanofluid

This article highlights the influence of mixed convection, Hall current and magnetic field on peristaltic motion of Powell-Eyring nanofluid in the symmetric channel. Energy equation include the viscous dissipation, Ohmic heating and thermal radiation effects. Brownian motion and thermophoresis are considered to explore the nanofluid characteristics. Velocity slip, thermal jump and zero mass flux conditions are considered on the boundary wall. Further temperature dependent viscosity is taken into account. Lubrication approach is used to simplify the dimensionless form of governing equations. Final form of equations are solved numerically. Velocity, temperature, concentration and entropy generation behaviors are studied with the help of graphs. Temperature depicts increasing behavior for higher magnetic field whereas the opposite trend is noticed for Hall effects.

Automated summary

This study investigates the influence of mixed convection, Hall current, and magnetic field on the peristaltic motion of Powell-Eyring nanofluid in a symmetric channel, considering factors such as viscous dissipation, thermal radiation, Brownian motion, and thermophoresis. Numerical solutions show that higher magnetic fields lead to an increase in temperature, while Hall effects exhibit the opposite trend.
