摘要：

Purpose - This work aims to focus on the study of natural convection heat transfer characteristics in a vertical wall embedded in a non-Darcy porous medium filled with nanofluids. Design/methodology/approach - The governed partial differential equations are transformed into ordinary differential equations which are obtained by similarity solution and then have been solved through homotopy analysis method. Findings - The results show that Cu-water as nanofluid enhances the local Nusselt number more than other nanofluids. Originality/value - Nanoparticles and nanofiuid enhance the local Nusselt number.
