Abstract


In this paper, we investigated the effect of Hall on the peristaltic pumping of a hyperbolic tangent fluid in a planar channel under the assumption of long wavelength. The expressions for the velocity and axial pressure gradient are obtained by employing perturbation technique. The effects of Weissenberg number, power-law index, Hall parameter, Hartmann number and amplitude ratio on the axial pressure gradient, time-averaged volume flow rate and the friction force at the wall are analyzed with the help of graphs.


Keywords
