چکیده انگلیسی
Effects of heat absorption and nanoparticle on natural convection heat transfer along vertical wavy surface have been investigated. Transport equations have been solved numerically by accurate implicit finite difference scheme. The skin friction and Nusselt number are plotted against variation of several parameters for two types of nanoparticles namely, alumina (Al2O3) and magnetite (Fe3O4). The impact of nanoparticle concentration on flow and heat transfer process in the problem under investigation has been studied in detail. The results indicate that Al2O3-water nanofluid exhibits higher skin friction and heat transfer rate in comparison to Fe3O4 water based nanofluid. The influence of heat absorption parameter is to increase the heat transfer rate and decrease the skin friction coefficient. For heat absorption case percent change in the skin friction and Nusselt number for two nanoparticles is shown in tabular form where comparison to the flat plate (pure fluid) and wavy surface (pure fluid) cases have also been made. The present results have been validated by producing the results available in literature and a very good agreement is observed.
