Modeling Electrification of Nanoparticles in Free Convective Nanofluid Flow

Abstract

Free convection boundary layer nanofluid flow past a vertical flat plate with electrification is investigated. Electrification phenomenon of nanoparticles is considered in two component Buongiorno’s model.The PDEs of flow field are changed into a system of coupled ODEs through similarity analysis and solved with respect to transformed boundary conditions using MATLAB bvp4c solver. The effects of governing dimensionless parameters such as Thermophoresis parameter, Electrification parameter and Brownian motion parameter on concentration and temperature distributions are examined graphically. It is observed that the dimensionless heat and masstransfer coefficients are enhanced whereas the normalized temperature of nanofluid and non-dimensional nanoparticle concentration are reduced for larger values of Electrification parameter.
