...S. K. Som; N. Y. Sharma A theoretical model of exergy balance based on availability transfer and flow availability in the process of spray combustion in a gas turbine combustor has been developed to evaluate the total thermodynamic irreversibility and second law efficiency of the process at various...

... Optimization Second Law Thermodynamics The thermodynamic optimization of heat exchangers has attracted considerable attention during the past two decades, and is now an established subfield in heat transfer and engineering thermodynamics. It is now recognized as the mechanism for the generation...

... the principle recognized in this work is new on the currently accepted background. The approach to equilibrium, the direction of time, or the difference between before and after, is the domain covered by the second law of thermodynamics. The objective and constraints (constructal) principle invoked in this work...
