What is Insight Into Recompression Brayton Cycle about?

Abstract Recompression cycles have the potential to offer high performance when design parameters such as feasibility, performance, and compactness are considered. These cycles have recently gained attention especially in nuclear and concentrating solar power plants because of their high efficiency and environmentally friendly. A study has been done to investigate and learn more about recompression cycles. In this paper, a recompression Brayton cycle has been analyzed by performing parametric studies on the effectiveness of recuperators, pressure ratio, and split ratio as well as other input variables. To understand the relations between these factors and the performances of the cycle, argon was used as a working fluid because of its constant specific heat. The solution to temperatures at each state has been derived analytically, which is presented as a function of independent input variables. Thermal efficiency and exergy efficiency of this cycle have been determined in these analyses. The model indicates following results: entropy generation of recuperators is lower at a minimum split and decreases with increasing effectiveness. When the cycle is optimized for maximum efficiency
