Non-linear radiative flow of three-dimensional Burgers nanofluid with new mass flux effect

Abstract

This article peruses the heat and mass transfer characteristics of three-dimensional steady flow of Burgers nanofluid over a bidirectional stretching surface. The convective boundary and nanoparticles mass flux conditions are considered. Additionally, the impact of non-linear thermal radiation and heat generation/absorption is delved. Further, the most recently proposed model for nanofluid is deliberated that necessitate nanoparticle volume fraction at the wall to be inertly rather than vigorously controlled. A set of similarity transformation is presented to alter the boundary layer equations into self-similar form and then tackled analytically by employing the homotopy analysis method (HAM). The effects of various controlling parameters to the heat and mass transfer characteristics are presented through graphs and scrutinized. The analytical out comes for the wall temperature gradient (Nusselt number) are calculated and presented through tables. It is seen that for enlarging values of the Brownian motion parameter lead to an attenuation in the concentration field as well as corresponding concentration boundary layer thickness. Likewise, it is noticed that the concentration field fall off hastily corresponding to Deborah number (β3) in comparison to Brownian motion parameter. Moreover, in order to perceive the validity of the existing effort, the numerical outcomes are compared with the analytical solutions attained by the HAM and noted an outstanding agreement for the limiting cases.
