Abstract
In this paper, we have explained the ciliary motion of a Carreau fluid inside a symmetrical channel with ciliated walls. Carreau fluid equations for the two dimensional channel are interpreted by employing the low Reynolds number and long wave-length approximations. The analytical series solutions are found by employing the Homotopy perturbation method. Solutions are presented through graphs. The results for the distinct values of the constants are described by generating graphs of velocity, pressure gradient, pressure rise and stream lines. (C) 2016 Author(s).
