Abstract:

This paper focuses on electrification of particles, terms related to the heat added to the system to slip-energy flux in the energy equation of particle phase and heat due to conduction and viscous dissipation in the energy equation of the particle phase in modeling the steady laminar boundary layer flow and heat transfer of a dusty fluid over an inclined stretching sheet. Viscous dissipation, internal heat generation/absorption and effect of electrification of particles are considered in the energy equation. The governing equations are reduced to a set of ordinary partial differential equation by using suitable similarity transformations along with pertinent boundary conditions. They are solved numerically by Runge Kutta forth order method along with shooting technique. Finally the effect of the pertinent physical parameters like fluid-particle interaction parameter, Grashof number, Prandtl number, Eckert number and diffusion parameter on the flow and heat transfer characteristics are computed and presented graphically and also in tabular form. The rate of heat transfer at the surface and skin friction increase with increasing value of electrification parameter.
