In heat exchanging devices of ammonia–water based power generation cycles for the recovery of waste heat in the form of sensible energy, assessment of pinch point (PP) is far more complicated compared to the case of working fluid of pure substance. In this study, efficient and novel method is...

Thermoelectric generators (TEGs) make use of the Seebeck effect in semiconductors for the direct conversion of heat into electrical energy, being of particular interest for high reliability systems or for waste heat recovery. Although several TEG models can be found in the literature, many of...
