The exergy of stratified thermal energy storages
TLDR
In this paper, the performance of TES systems incorporating thermal stratification is described, along with the resulting insights and benefits, and six temperature-distribution models for stratified TESs are considered (linear, stepped, continuous-linear, general linear, basic three zone and general three-zone) to evaluate energy and exergy contents.About:

The Exergy Method of Thermal Plant Analysis
TL;DR: The Exergy Method as mentioned in this paper is a method of thermodynamic analysis in which the basis of evaluation of the thermodynamic losses follows from the Second Law rather than the First Law of Thermodynamics and has gained in the last few years many new followers, both among practising engineers and academics.
