A Boundary layer flows of non-Newtonian Williamson fluid

Abstract

In this investigation, the steady boundary layerow of Williamson uid is studied. The nonlinear partialdifferential equations are transformed into ordinary differ-ential equations by using similarity transformations, thenthe series solution are obtained by employing homotopyanalysis method (HAM), in the four ow problems of aWilliamson uid namely Blasius, Sakiadis, stretching andstagnation point ows. The inuence of Weissenberg num-ber on the velocity and skin friction coecient is analyzedthrough graphical and tabular results
