The present work deals with the peristaltic flow of a tangent hyperbolic fluid in an asymmetric channel. The flow equations have been derived for the tangent hyperbolic fluid. Analysis has been done in the presence of convected boundary condition. The governing nonlinear partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations using similarity transformations and then tackled analytically using the perturbation technique. The main focus has been given to the effects of the Biot number, the power law index and the Weissenberg number. Graphical results for velocity, temperature, pressure rise and trapping are obtained and analyzed in detail.
