Entropy generation optimization and activation energy in flow of Walters-B nanomaterial

In present research, we concentrated on the characterization of Walters-B nanofluid flow to investigate the irreversibility mechanism. Energy equation incorporated with radiation effects and heat generation phenomena. Influence of activation energy is discussed using modified Arrhenius energy term along binary chemical reaction. The consequences of thermophoresis, Brownian motion and viscous dissipation on fluids velocity, temperature of fluid particles and concentration of involved chemical species. Set of ordinary differential equations are obtained by implementing appropriate similarity variables. Governing mathematical model is solved using homotopy analysis method. Flow behavior is analyzed through Nusselt number, coefficient of drag force and mass transfer rate.
