A Nanofluid Boundary Layer Flow Over a Stretching Body in the Presence of Porous Medium

Abstract

A numerical approach is presented to investigate fluid concentration, velocity and temperature like flow characteristics for the nano fluid boundary layer flow over a stretching sheet in the presence porous medium. The equations of ordinary differentiation are obtained from the governing equations of partial differentiation using similarity transformations. The reduced equations of ordinary differentiation have solved numerically using both Spectral Collocation Method and Shooting Technique which involves R-K Fehlberg and N-R method. The computation results are drawn for dimensionless parameters like Lewis number, Brownian motion parameter, thermophoresis parameter, thermal diffusivity, Prandtl number and porous parameter on the fluid flow, concentration and temperature characteristics. The computation results dictates that the enhancement of the porous parameter diminishes the flow whereas temperature and concentration enhance in this region. Due to nanofluid there is a rise in thermal conductivity of fluid flow. The polymer drawing and extrusion, casting, hot rolling, metal cooling and lot of engineering processes made use of the computational results and information understood very well.
