A steady-state free convective flow of Cu-water nanofluid over an inclined flat plate with active control of nanoparticle concentration has been studied numerically. Buongiorno’s nanofluid model has been considered with nanoparticle electrification. A similarity transformation is introduced to reduce the governing non-linear partial differential equation into coupled ordinary differential equations which are then solved numerically using bvp4c function of MATLAB software. Validation of the result has been made by comparing the present results with the results obtained from the previous studies. The effects of angle of inclination, buoyancy ratio parameter, Brownian motion, thermophoresis and electric field on different flow parameters are depicted through figures and tables. It is observed that the impact of nanoparticle electrification is to enhance the non-dimensional skin friction coefficient as well as both heat and mass transfer rates in active control cases.
