Exergy Analysis: Principles and Practice

Journal of Engineering for Gas Turbines and Power, 1994
The importance of the goal of developing systems that effectively use nonrenewable energy resources such as oil, natural gas, and coal is apparent. The method of exergy analysis is well suited for furthering this goal, for it enables the location, type and true magnitude of waste and loss to be determined.

EXERGY ANALYSIS OF PSYCHROMETRIC PROCESSES

2007
Psychrometrics is the science of air and water vapor and deals with the properties of moist air. A thorough understanding of psychrometrics is of great significance. It plays a key role not only in heating, cooling, and humidification processes and the resulting comfort of building occupants but also in building insulation, roofing properties, and the ...

Generalization of exergy analysis

Applied Energy, 2015
Abstract Exergy analysis, which provides means of calculating efficiency losses in industrial devices, is reviewed, and the area of its validity is carefully discussed. Consequently, a generalization is proposed, which holds also beyond the area of applicability of exergy analysis.

Nomenclature for Exergy Analysis

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 1995
In this paper a system of names and symbols for exergy analysis is put forward for further discussion. The concept of exergy is shown to be dependent on that of the environment. The conceptual environment provides a natural reference state for calculating absolute values of exergy.

Fundamentals of Exergy Analysis

2017
Conservation laws are important tools in analysis of thermal processes. In engineering practice, substance conservation law and energy conservation law are commonly used. Exergy analysis based on first and second law of thermodynamics are still rarely applied in engineering and industrial practices.

Exergy analysis of cryogenic air separation

Energy Conversion and Management, 1998
An exergy analysis is performed to analyse the possibilities of fuel saving in the cryogenic distillation process, which is the main method of air separation. It is shown that more than half of the exergy loss takes place in the liquefaction unit and almost one-third in the air compression unit.

Exergy analysis for a petroleum refinery : cumulative exergy consumption analysis

The aim of cumulative exergy consumption (CExC) analysis is to evaluate the qualitative amount of energy required to produce the specific products of the process under consideration. Therefore, the CExC indices of the products under consideration can be compared to those evaluated from different processes. The results obtained can be implemented to the

Exergy analysis of ramjet

Thermophysics and Aeromechanics, 2009
An exergy analysis of possible regimes of energy supply to the air flow in the ramjet duct is carried out. A condition for the supply of a given heat amount to supersonic flow and a condition of the passage across the sound velocity are obtained for a duct with variable cross-sectional area.

Energy and Exergy Analysis

2009
In this chapter, an overall view of energy matrices and embodied energy, with and without balance of system (BOS) is discussed so that the net useful electrical energy available over the life of the PV system can be evaluated. As we know that the quality of energy is more important than quantity.
