Abstract
Examination has been made to explore the impact of the induced magnetic field of peristaltic flow for an incompressible Williamson fluid in the curved channel. Formulation of problem is constructed in wave frame of reference. HPM (homotopy perturbation method) is utilized for explaining the continuity equation, induction equation and equation of motion after utilizing the approximations of long-wavelength and low-Reynolds number. Explicit analytical expressions for pressure gradient and stream function, magnetic force function, induced magnetic field and current density are developed. The effects of embedded parameters portrayed and discussed by using graphical approach.
•Smaller velocity for Williamson fluid than the Newtonian fluid.•Pressure rise is larger for Williamson fluid than viscous fluid.•Magnitude of induced magnetic field is smaller for Williamson fluid in comparison to viscous fluid.•Symmetry of quantities of interest such as velocity, current density, induced magnetic field at r=0 is disturbed due to curvature.
