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

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.

Forced convection analysis for generalized Burgers nanofluid flow over a stretching sheet

This article reports the two-dimensional forced convective flow of a generalized Burgers fluid over a linearly stretched sheet under the impacts of nano-sized material particles. Utilizing appropriate similarity transformations the coupled nonlinear partial differential equations are converted into a set of coupled nonlinear ordinary differential equations. The analytic results are carried out through the homotopy analysis method (HAM) to investigate the impact of various pertinent parameters for the velocity, temperature and concentration fields. The obtained results are presented in tabular form as well as graphically and discussed in detail. The presented results show that the rate of heat transfer at the wall and rate of nanoparticle volume fraction diminish with each increment of the thermophoresis parameter. While incremented values of the Brownian motion parameter lead to a quite opposite effect on the rates of heat transfer and nanoparticle volume fraction at the wall.
