...Adrian Dumitrescu; T. W. Lee; R. P. Roy A computational model of a hybrid pressurized solid oxide fuel cell (PSOFC) generator/gas turbine power plant is developed using classical thermodynamic analysis in conjunction with electromechanical, fluid-mechanical, and heat transfer simulations...

..., and another one is a two-stage syngas cooling entrained-flow gasifier. The conservation of energy (first law of thermodynamics) and the quality of energy (second law of thermodynamics) for the systems are both investigated. The results of exergy analysis provide insights about the potential targets...

... effective pressure is theoretically the best engine for small capacity reciprocating heat engine. However, the practical Stirling engine performance is far from the ideal. As an alternative, practical heat engines based on thermodynamic cycles (without regeneration) other than the Stirling cycle have been...

...Joseph J. Boza; William E. Lear, Ph.D.; S. A. Sherif, Ph.D. A thermodynamic performance analysis was performed on a novel cooling and power cycle that combines a semiclosed gas turbine called the high-pressure regenerative turbine engine (HPRTE) with an absorption refrigeration unit. Waste heat...

After an overview of the methods available in the literature, dealing with a multidimensional analysis of energy system, the authors propose a quantitative approach based on the use of two different thermodynamic based utility functions. The utilization of those functions...
