Abstract
A closed-form model for the second-law-based thermoeconomic optimization of a sensible heat storage system, in which the energy is stored in a large liquid bath from a hot-gas source, is discussed with an example problem. The results are compared with those obtained from Bejan’s analysis to illustrate usefulness of the present approach. The influence of important parameters on the optimum number of heat transfer units Ntu,opt, and dimensionless charging time θopt, are presented in a graphic form.
