Abstract Pumped thermal electricity storage is a thermo-mechanical energy technology that has emerged as promising option for large-scale (grid) because of its lack geographical restrictions and relatively low capital costs. This paper focuses on 10 MW Joule-Brayton pumped system with liquid stores performs detailed conventional advanced exergy analyses this system. Results the analysis recuper...

In this paper, a comparison of exergetic models between two hot air engines (a Gamma type Stirling prototype having a maximum output mechanical power of 500 W and an Ericsson hot air engine with a maximum power of 300 W) is made. Referring to previous energetic analyses, exergetic models are set up in order to quantify the exergy destruction and efficiencies in each type of engine. The repartit...

Our physical environment is endowed with unlimited amount of natural and artificial sources of energy at various low exergetic levels which leaves them almost impossible to be thermally utilized at such source states. The thermal upgrading of these low exergetic energy sources could render them amenable to various practical thermal usages. This paper provides a comparative study through simulat...

Absorption chillers present opportunities to utilize sustainable fuels in the production of chilled water. An assessment of the steam driven absorption chiller at the University of Idaho, was performed to quantify the current exergy destruction rates. Measurements of external processes and flows were used to create a mathematical model. Using engineering equation solver to analyze and identify ...

The Relative Gain Array (RGA) provides a quantitative comparison of interactions between control loops. It shows steady state interactions between control loops. The thermodynamic concept of exergy can be used to analyse a process in terms of its efficiency. The Relative Exergy Array (REA) that measures both the relative exergetic efficiency and controllability of a process has been proposed (2...
