A Boundary layer flows of non-Newtonian Williamson fluid

[摘要] In this investigation, the steady boundary layer flow of Williamson fluid is studied. The nonlinear partial differential equations are transformed into ordinary differential equations by using similarity transformations, then the series solution are obtained by employing homotopy analysis method (HAM), in the four flow problems of a Williamson fluid namely Blasius, Sakiadis, stretching and stagnation point flows. The influence ofWeissenberg number on the velocity and skin friction coeffcient is analyzed through graphical and tabular results.
