Analysis of double diffusion natural convection in an enclosure filled with alumina water nanofluid using Buongioro's two phase model

Abstract

Purpose The purpose of this study is to apply Buongiorno’s two phase model to analyse double diffusion natural convection in a square enclosure filled with nanofluids. Design/methodology/approach A computational code based on the SIMPLE algorithm and finite volume method is used to solve the non-dimensional governing equations. Findings The nanoparticle plays a crucial role when thermal and solutal buoyancy forces are equal and opposing. Originality/value This is the first paper to apply Buongiorno’s two phase model for double diffusion natural convection in enclosures filled with nanofluids.
