Краткое описание

The aim of the present paper is to study heat conduction in a nanofluid layer containing low volume concentration of Al2O3 nanoparticles with regard to the migration of nanoparticles due to Brownian diffusion and thermophoresis. To do this, both known heat flux and known temperature boundary conditions are investigated. All of the properties are assumed to be temperature- as well as particle concentration-dependent. The energy equation along with the particle concentration equation is nondimensionalized and solved numerically. The effects of temperature difference and heat flux magnitude on nonuniform distribution of nanoparticles, the local conductivity, and temperature distribution of nanofluid are shown.
