Energy, exergy and advanced exergy analysis of a milk processing factory [PDF]

Energy, 2018
Abstract Energy, exergy and advanced exergy methods were used to analyse a milk powder production facility. While a conventional energy analysis is used to map the energy flows and to suggest possibilities for process integration through pinch analysis, an exergy analysis identifies the locations and magnitudes of thermodynamic irreversibilities.

Exergy Analysis in Hydrogen‐Air Detonation [PDF]

Journal of Applied Mathematics, 2012
The main goal of this paper is to analyze the exergy losses during the shock and rarefaction wave of hydrogen‐air mixture. First, detonation parameters (pressure, temperature, density, and species mass fraction) are calculated for three cases where the hydrogen mass fraction in air is 1.5%, 2.5%, and 5%.

Thermal Exergy Analysis of a Building

Energy Procedia, 2014
AbstractExergy analysis has been contemplated to evaluate the direct energy impact of a building on the environment. The authors’ approach is to consider the building as a “black box” that needs exergy. The surrounding and the Environment are closed systems, in thermodynamic equilibrium between them. The building is transient open system.
