Investigation of nanofluid conveying porous medium through non-parallel plates using the Akbari Ganji method

Abstract

Abstract This paper presents the study on the Jeffery Hamel nanofluid flow and heat transfer through non-parallel channel taking into account radiation effect. The fluid with porous medium flowing through the non-parallel channel is formulated utilizing momentum and energy equations. Since the model obtained are nonlinear, higher order systems of equations, the Akbari Ganji novel approximate method is adopted in this paper. As reported in the graphical representation of the result, it is depicted that the porous medium limits flow due to increased dynamic viscosity leading to pressure drop while the radiation parameter enhances heat loss through the non-parallel plates. This evidently leads to energy loss. The Akbari–Ganji method is used in this study to investigate the parametric behavior of rheological parameters on the flow and heat transfer owing to its high accuracy. Results obtained in this study compared against analytical and numerical solution obtained in literature shows satisfactory conclusion. Therefore, results from this paper may be useful in advancing studies of nanofluid with porous medium.
