Abstract: A steady boundary layer flow with heat and mass transfer of Cu-water nanofluid over a stretching cylinder is studied by considering the Buongiorno’s two-component non-homogeneous model with the inclusion of electrification of nanoparticles and viscous dissipation. The governing equations of flow field are solved numerically using similarity transformations followed by sixth order Runge-Kutta method with shooting scheme. The influence of Brownian motion parameter, thermophoresis parameter, electrification parameter, curvature parameter, Eckert number, Lewis number on the velocity, temperature and concentration profiles, skin friction coefficient, Nusselt number and Sherwood number are investigated and the corresponding numerical results are depicted through figures and in tabular forms. It is observed that electrification of nanoparticles have a significant effect on the flow, heat and mass transfer characteristics as well as skin friction coefficient. An increase in electrification parameter enhances the velocity distribution, reduced skin friction coefficient, reduced Nusselt number and reduced Sherwood number whereas reduces the temperature and concentration distributions. |
