Cubic auto-catalysis chemical reaction in non-Newtonian nanolubricant flow over a convectively heated rotating porous disk

This paper concerns with the numerical investigation on a boundary layer flow of nanolubricant/liquid flow over a convectively heated rotating disk. Following that, the research was supported by the inclusion of the convection process as well as the influence of heterogeneous and homogeneous reactions on the flow of the nanolubricant/liquid in concern. A comparative analysis is made in terms Zinc Oxide (ZnO)-Society of Automotive Engineers 50 nanolubricant and Zinc Oxide-Kerosene using two different models. Transforming the governing nonlinear equations yields the nonlinear ODE set. Numerical investigations use Runge-Kutta method. Flow, temperature and concentration field controlling factors are also explored numerically. The heat transport and shear stress and characteristics are evaluated for important factors. Results reveals that, ZnO-SAE50 nanolubricant shows augmented heat transport than ZnO-Kerosene nanoliquid for increased values of Q. But reverse trend is seen for increased Biot number values. Nanolubricant shows improved heat transport rate than ZnO-Kerosene nanoliquid for augmented values of heat source and porosity parameters.

Automated summary

This paper numerically investigates the boundary layer flow of nanolubricant/liquid over a convectively heated rotating disk. The study considers the convection process and the influence of heterogeneous and homogeneous reactions. A comparative analysis is made using two different models with Zinc Oxide (ZnO)-Society of Automotive Engineers 50 nanolubricant and Zinc Oxide-Kerosene. The governing nonlinear equations are transformed into a nonlinear ODE set, and numerical investigations use the Runge-Kutta method. Factors such as flow, temperature, and concentration fields are explored numerically, and the heat transport and shear stress characteristics are evaluated. Results reveal that the ZnO-SAE50 nanolubricant shows enhanced heat transport and the nanolubricant performs better in terms of heat transport rate with increased heat source and porosity parameters.
