A parametric study to investigate the impact of electrification and radiation inside a thermal
particulate boundary layer, where the flow is due to an unsteady stretching sheet in
presence of non-uniform heat source/sink. Both the fluid as well as the particles are
assumed to be gray, emitting and absorbing radiation. Again, neither the fluid is considered
in electric medium nor supplied by an external electric force. But, due to the random motion
of the particles ie, the interaction between particleparticle, particle-fluid and particle-wall, a …

A parametric study to investigate the impact of electrification and radiation inside a thermal particulate boundary layer, where the flow is due to an unsteady stretching sheet in presence of non-uniform heat source/sink. Both the fluid as well as the particles are assumed to be gray, emitting and absorbing radiation. Again, neither the fluid is considered in electric medium nor supplied by an external electric force. But, due to the random motion of the particles ie, the interaction between particleparticle, particle-fluid and particle-wall, a tribo-electrification occurred. As on impact, both the fluid and particles are electrified though the flow has been considered in a neutral medium. Hence, a balanced mathematical model of highly non-linear partial differential equations has been formulated for two-phase unsteady boundary layer considering the above parameters/impacts on both the phases. An appropriate similarity transformation has been employed to transfer the governing equations into ordinary differential equations and solved numerically by built in solver Bvp4c of MATLAB. An excellent agreement between the present and previous literature has been made to validate the result. Moreover, the influence of Electrification parameter, Radiation parameter, Internal heat source/sink parameter on the rate of heat transfer and other flow characteristics has been analyzed.
