Entropy anatomization on Marangoni Maxwell fluid over a rotating disk with nonlinear radiative flux and Arrhenius activation energy

Numerical analysis is performed for an incompressible Marangoni Maxwell nanofluid flow model under the implications of thermophoresis, brownian motion and nonlinear radiation over a convectively heated rotating disk. The second law of thermodynamics is also incorporated. The system that comprises differential equations of partial derivatives is remodeled into the system of differential equations via similarity transformations and then solved numerically through the Runge-Kutta-Fehlberg with shooting technique. The physical parameters, which emerges from the derived system are discussed in graphical formats. The significant outcomes of the current investigation are that the velocity filed decays for a higher magnetic parameter, the heat transfer rate is enhanced with the incremental values of radiation parameter and Prandtl number. Further, the entropy generation rate decreases with the fluid parameter while that peters out the Bejan number.
