The supercritical CO2 is used as working fluid for power system cycle. This paper presents thermodynamic performance analysis results on Brayton Based the assumptions of relevant initial parameters, mathematical models compressor, turbine, recuperator and heater are constructed, thermal efficiency regenerative cycle recompression calculated analyzed. reveal that higher than simple effects inlet...

As an essential component of the SCO2 recompression Brayton cycle, recuperator has a significant impact on efficiency and stability entire cycle system. The printed circuit heat exchanger (PCHE) is most suitable for in cycle. To investigate effects structural parameters asymmetric airfoil fins thermo-hydraulic performance PCHEs, simplified three-dimensional numerical simulation models PCHE with...

Abstract Efficiency is a crucial factor for power cycles. Generally, in the same temperature range, cycle efficiency basic organic Rankine (ORC) higher than similar trilateral flash (TFC) almost all working fluids and heat source/heat sink pairs. According to some recent results, by using super dry fluids, thermal of TFC can outperform its ORC counterpart at high temperatures. This study perfor...

The purpose of this simulation study is the examination a solar-driven power cycle that driven by collectors with evacuated tubes. an organic Rankine (ORC) works cyclopentane. novelty use reheating in order to enhance its thermodynamic efficiency, while also has recuperator. Moreover, compared conventional ORC determine performance enhancement examined idea. analysis done developed program Engi...
