Investigation on the effect of mixtures physical properties on cycle efficiency in the CO2-based binary mixtures Brayton cycle
L Wang, L Pan, J Wang, D Chen, Y Huang… - Progress in Nuclear …, 2022 - Elsevier
S–CO 2 recompression Brayton cycle has attracted much attention with the development of
compact heat exchangers. However, the critical point of CO 2 is a constraint on the minimum
cycle condition. Mixing additional gas into pure CO 2 working fluids could reduce the critical
point and bring improvement potential of the cycle efficiency. However it is not determined
what kind of mixtures can improve cycle efficiency; and there is no criterion for choosing
proper binary mixtures components. In this study, the feasibility of using mixtures physical …
