The present article addresses peristaltic flow of Sisko nanofluid in a curved channel. Fluid is conducting by an applied radial magnetic field. Joule heating effect in energy equation modeling is considered. Slip conditions at the boundaries are employed. Numerical simulations through NDSolve technique are performed. Graphical results for the sundry parameters are displayed and discussed. (C) 2017 Elsevier Ltd. All rights reserved.
