and thermal efficiencies for these cycles was performed. The findings demonstrated that the highest thermal efficiency was … achieved using the recompression Brayton cycle, at June noontime. The maximum integrated system thermal efficiency using this … cycle was 40% while the maximum thermal efficiency of this cycle alone was 52%. The regenerative Brayton cycle, although …

To improve their efficiency is of vital importance for the widespread application of TEG (thermoelectric generators). A … optimum efficiency and geometrical dimensions of the STEG (segmented thermoelectric generator) module operating between 300 K … peak efficiency is about 11.2% when the load resistance is close to the internal resistance, which matches well with the …

directly coupled to organic Rankine cycle turbine. The energy efficiency of the system is found to be 56.5% and the exergy … efficiency 20.3%. The largest exergy destructions are found to occur in both combustion chamber and boiler. The variations in …
