Abstract
In this study we have presented the comparative analysis of the oscillatory stagnation point flow of nanofluids. Both the phase flow model and Buongiorno model are discussed for oscillatory stagnation point flows and a comparison between experimental model and theoretical model is presented. The resulting partial differential equations for oscillatory two-dimensional flows are simplified in a fixed frame and a moving frame of reference subject to the assumed form of solutions. The homotopy analysis method is used to solve the reduced system of coupled nonlinear ordinary differential equations. The consequences are examined through graphs and tables. It is also found that comparatively both the Boungiorno nanofluid model and phase flow model are of compatible order for a special set of parameters but generally such results do not hold.
