Abstract: In this paper, the problem of steady laminar natural convective flow of Cu-water non-homogeneous nanofluid passed over a vertical flat plate has been studied numerically using modified Buongiorno’s model consisting electrification of particle along with the internal heat generation. The governing equations are reduced into non-linear ordinary differential equations, which are solved numerically. Numerical results for the dimensionless velocity, temperature, concentration, reduced Nusselt number and reduced Sherwood number are obtained and displayed graphically for pertinent parameters to show interesting aspects of the solution. Moreover, it is observed that the heat generation and electrification of particles could be a possible mechanism for enhancement of thermal conductivity apart from Brownian motion and thermophoresis suggested by Buongiorno. Moreover enhancement of thermal conductivity is more for Cu-water nanofluid. |
