Natural convection from a vertical wall embedded in a non-Darcy porous medium filled with nanofluids

Abstract

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 nanofluid enhance the local Nusselt number.
