Abstract

The optimal use of energy is the critical objective in the building of thermal devices which are useful both in engineering and industrial operations. To achieve this objective, considerable attention should be paid to minimization of entropy production in the processes. In view of this, entropy generation in thermal boundary layer fluid flow of an electrically conducting micropolar fluid over a convectively heated nonlinear stretching sheet being influenced by viscous dissipation and thermal radiation has been analyzed in this study. The formulated governing equations of the flow, heat transfer and entropy generation are converted to ordinary differential equations by similarity transformation procedures. Thereafter, the resulting equations are computationally integrated by means of shooting techniques accompanied by fourth order Runge-Kutta algorithms entrenched in a symbolic software Maple 2016. The imapct of various controlling physical parameters on the fluid flow, temperature distribution, entropy generation, Bejan number and other quatities of engineering interest are discussed through graphs and tables. The facts from the study show that heat transfer irreversibility is stronger than that of viscous dissipation and Joule heating as the radiation parameter rises while the nonlinear stretching parameter influence is to diminish the transfer of heat.
