ABSTRACT
Laminar mixing of a two-dimensional plane wall jet of particulate suspension in an incompressible carrier fluid has been considered. The basic equations are of the boundary layer type and include the diffusion equation for sub micron particles to investigate the flow field. The drag force due to slip, finite volume fraction ,heat due to conduction and viscous dissipation in the particle phase energy equation have been introduced to study their effect on skin friction & heat transfer. The governing equations are solved by taking perturbations on Schlirchting’s model. Again, the effects of Prandtle number ,Eckrt number, Nusselt number, size of the particles ,Material density of the particles and diffusion parameters on the velocity and temperature field for both phases have shown through figures and tables. It is observed that Nusselt number always increases with the increase of the above parameters, and heat always transform from fluid to plate in all the cases.
