Synergetics: The cooperative phenomenon in multi-compressions S-CO2 power cycles
Energy Conversion and Management: X, 2020 Mature power plant uses regenerative steam Rankine cycle to achieve excellent performance, but there is a lack of general approach for gas Brayton cycle. Here, synergetics is introduced to construct multi-compressions S-CO2 cycle for the first time.

How to Construct a Combined S-CO2 Cycle for Coal Fired Power Plant?
Entropy, 2018 It is difficult to recover the residual heat from flue gas when supercritical carbon dioxide (S-CO2) cycle is used for a coal fired power plant, due to the higher CO2 temperature in tail flue and the limited air temperature in air preheater. The combined
