Effects of induced magnetic field for peristaltic flow of Williamson fluid in a curved channel

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. (C) 2020 Elsevier B.V. All rights reserved.
