Abstract:
We have analyzed an incompressible Sisko fluid throughanaxisymmetricuniformtubewithasinusoidal wave propagating down its walls.The present analysis of non-Newtonian fluid is investigated under the considerations of long wavelength and low Reynolds number approximation.The analytic solution is obtained using(i) the regular perturbation method(ii) the Homotopy analysis method(HAM).The comparison of both the solutions is presented graphically.The results for the pressure rise,frictional force and pressure grad...
