Abstract

The level of irreversibility that takes place in any thermal process is measured by means of entropy generation. In different industrial and engineering sectors, the phenomena of heating and cooling are very crucial in various energy and electronic devices. In the light of this, the optimization of entropy production with the aim of preventing any energy loss, which can affect the performance of a particular system is very necessary. Hence, this study investigates entropy generation analysis in an electrically conducting and dissipative micropolar fluid over a nonlinear vertically stretching sheet being influenced by thermal radiation, non-uniform heat source/sink, variable magnetic field strength and variable electrical conductivity. The dimensionless equations governing the flow and heat transfer are computationally solved using shooting techniques alongside fourth order Runge-Kutta algorithms embedded in Maple 2016 software. The effects of the main physical parameters on the velocity, temperature, microrotation, entropy generation and Bejan number are graphically displayed and discussed. 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 whereas the opposite is the case with rising values of the micropolar and Brikman parameters.
