Extension of Blasius Newtonian Boundary Layer to Blasius Non-Newtonian Boundary Layer

Abstract

Blasius equation is very well known and it aries in many boundary layer problems of fluid dynamics. In this present article, the Blasius boundary layer is extended by transforming the stress strain term from Newtonian to non-Newtonian. The extension of Blasius boundary layer is discussed using some non-newtonian fluid models like, Power-law model, Sisko model and Prandtl model. The Generalised governing partial differential equations for Blasius boundary layer for all the above three models are transformed into the non-linear ordinary differential equations using the one-parameter deductive group theory technique. The obtained similarity solutions are then solved numerically. The graphical presentation is also explained for the same. It concludes that velocity increases more rapidly when the fluid index is moving from shear thickninhg to shear thininhg fluid.
