“…Naterer and Camberos [6] discussed the utility of entropy and the second law as reliable and systematic tools for optimal energy usage and choice of technologies for a multitude of applications in compressible flows, as well as for problems with phase change heat transfer. Lior and coworkers [7] presented a review on the applications of exergy fields in transport processes, while the coupling between these fields was investigated by Chen and coworkers [8].…”

A critical factor in the design of combustion systems for optimum fuel economy and emission performance lies in adequately predicting thermodynamic irreversibilities associated with transport and chemical processes. The objective of this study is to map these irreversibilities in terms of entropy production for methane combustion. The numerical solution of the combustion process is conducted with the help of a Fluent 6.1.22 computer code, and the volumetric entropy production rate due to chemical reaction, viscous dissipation, and mass and heat transfer are calculated as post-processed quantities with the computed data of the reaction rates, fluid velocity, temperature and radiative intensity. This paper shows that radiative heat transfer, which is an important source of entropy production, cannot be omitted for combustion systems. The study is extended by conducting a parametric investigation to include the effects of wall emissivity, optical thickness, swirl number, and Boltzmann number on entropy production. Global entropy production rates decrease with the increase in swirl velocity, wall emissivity and optical thickness. Introducing swirling air into the combustion system and operations with the appropriate Boltzmann number reduces the irreversibility affected regions and improves energy utilization efficiency.

“…Another unique advantage of Eqn. (1) is that it allows designers to use local loss mapping to detect locations of high entropy production, thereby allowing local design changes of geometrical or other parameters to improve system efficiency (Naterer and Camberos [7]). …”
