Combined with a series of two-dimensional numerical simulations of a rotating detonation combustor (RDC) and calculations of cycle parameters, the pressure gain characteristics and cycle performance were investigated at different compressor pressure ratios in the study. The results showed that pressure gain characteristic of interstage bleeding RDC contributed to an obvious performance improvement in the rotating detonation gas turbine cycle compared with the conventional gas turbine cycle. The decrease of compressor pressure ratio had a positive influence on the performance improvement in the rotating detonation gas turbine cycle. With the decrease of compressor pressure ratio, the pressurization ratio of the RDC increased and finally made the power generation and cycle efficiency enhancement rates display uptrends. Under the calculated conditions, the pressurization ratios of RDC were all higher than 1.77, the decreases of turbine inlet total temperature were all more than 19 K, the power generation enhancements were all beyond 400 kW and the cycle efficiency enhancement rates were all greater than 6.72%.<\/jats:p>","DOI":"10.3390\/e21030265","type":"journal-article","created":{"date-parts":[[2019,3,8]],"date-time":"2019-03-08T11:21:59Z","timestamp":1552044119000},"page":"265","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Investigation of the Pressure Gain Characteristics and Cycle Performance in Gas Turbines Based on Interstage Bleeding Rotating Detonation Combustion"],"prefix":"10.3390","volume":"21","author":[{"given":"Lei","family":"Qi","sequence":"first","affiliation":[{"name":"College of Power and Energy Engineering, Harbin Engineering University, Harbin 150001, China"}]},{"given":"Zhitao","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Power and Energy Engineering, Harbin Engineering University, Harbin 150001, China"}]},{"given":"Ningbo","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Power and Energy Engineering, Harbin Engineering University, Harbin 150001, China"}]},{"given":"Yongqiang","family":"Dai","sequence":"additional","affiliation":[{"name":"College of Power and Energy Engineering, Harbin Engineering University, Harbin 150001, China"}]},{"given":"Hongtao","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Power and Energy Engineering, Harbin Engineering University, Harbin 150001, China"}]},{"given":"Qingyang","family":"Meng","sequence":"additional","affiliation":[{"name":"College of Power and Energy Engineering, Harbin Engineering University, Harbin 150001, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5174","DOI":"10.1016\/j.apm.2014.04.017","article-title":"Thermodynamic optimization of an irreversible regenerative closed Brayton cycle based on thermoeconomic performance criterion","volume":"38","author":"Durmusoglu","year":"2014","journal-title":"Appl.
