Abstract

Present investigation aims at scrutinizing the properties of heat and mass transfer phenomena of liquid thin film of Casson Nano fluid over elongated sheet under the influence of thermophorosis and Brownian motion. Casson Nano particle effect on thermophorotic force and on Brownian force is studied. Variables of similarity were induced to transmute partial differential equations into dimensionless equations and are resolved numerically by elegant method bvp 4c. Thin film thickness is calculated using MATHEMATICA for different values of critical parameters. Velocity profiles diminishes for higher values of Casson parameter and magnetic field parameter. The temperature escalates for higher values of Magnetic, Casson, thermal radiation, Brownian motion and thermophorosis parameters, whereas contrary effect with other parameters is observed. Impact of Skin friction, Sherwood and Nusselt numbers on the flow configurations for diverse critical parameters are exposed realistically via graphs. Arithmetical results that obtained in the current exploration are confirmed with previously explored values in marginal way.
