In this investigation, we intend to present the influence of electrification of nanoparticle along with thermal radiation on natural convection boundary layer flow of nanofluid along a vertical flat plate. The resulting momentum, energy, concentration equations are then made similar by introducing the usual similarity transformations. The similar equations are then solved numerically using sixth order Runge-Kutta method with shooting technique. Comparison result with previously published work is obtained and a good agreement has been found. The effect of various parameters on the dimensionless velocity, temperature and concentration profiles as well as the local values of Nusselt number and Sherwood number is displayed graphically and in tabular form. It is noted that the Nusselt number and Sherwood number increase with the increase of electrification parameter and radiation parameter.
