The peristaltic transport of nano-fluid under the influence of a magnetic field through a bio-fluidic channel is investigated numerically in this article. The geometry of the channel is assumed to be inclined and Oldroyd 4-constant fluid is flowing through it with Joule heating effects. The non-linear partial differential equations that lead the flow system are simplified using the approximations of long wavelength with low Reynolds number. The reduced coupled nonlinear are approximated by means of shooting technique. The obtained results for stream function, velocity, wall shear stress, nanop...
