Optimum exergy efficiency of solar collectors
International Journal of Energy Research, 1989 An optimum exergy efficiency is derived for flat-plate solar collectors as a ratio of exergy delivery of the collector to the maximum output exergy obtainable. It is a function of the optimum mass flow rate through the collector, which itself is obtained through an optimization of the exergy delivery of the collector.

Energy Science &Engineering, EarlyView.Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.

Energy Science &Engineering, EarlyView.A 4E comparison of PEMFC‐ORC and DMFC‐ORC systems shows that PEMFC‐ORC achieves 21% higher energy efficiency, while DMFC‐ORC obtains 31% higher exergy efficiency and 57% lower levelized cost of electricity. However, DMFC‐ORC emits nearly twice the annual carbon dioxide equivalent of PEMFC‐ORC.

Energy Science &Engineering, EarlyView.A novel combined cooling and power generation system is proposed by integrating organic Rankine cycle (ORC) with an absorption heat transformer, which is driven by combining geothermal energy and data center's waste heat. The system using R601a yielded the best overall performance, achieving an exergy efficiency of 40.34% and an annual cost of 130.29 k$
