Abstract
The influence of walls attributes on the peristaltic transport in a three dimensional rectangular channel has been incorporated in this article. It is found that the idea of three dimensional rectangular channel is quite helpful as compared with the two dimensional channels/tubes. The flow is considered to be incompressible and unsteady. Cartesian coordinate system has been employed to carry out the mathematical investigation. The obtained highly non-linear and non-homogeneous partial differential equations have been solved analytically by using homotopy perturbation method. The discussion on possible physical aspects of all emerging parameters appeared in the problems has been revealed through set of graphs sketched for velocity and stream function.
