The chemical looping combustion (CLC)-driven power generation system has great potential for application. In this study, a direct CLC-driven combined supercritical carbon dioxide and air Brayton cycle with near-zero emissions (CLC–sCO2–BC) is proposed. After revealing the thermodynamic performance advantages of proposed system, we comprehensively compared thermoeconomic CLC–sCO2–BC without preheating optimized two layouts using an immune genetic algorithm. results show that net advantage...
When the supercritical CO2 power cycle is employed in confined spaces, such as nuclear-powered ships and spacecraft, its size should be given priority. To estimate component size, one-dimensional heat exchanger model developed this study used a recompression integrated on small-scale lead-cooled fast reactor. A parameter analysis was performed to influence of several key parameters levelized cost electricity, thermal efficiency, system size. Moreover, four types multi-objective optimizations...
Implemented optimization and full life cycle economic analysis on the inter-stage pressure ratio were rarely paid attention to in supercritical carbon dioxide multi-stage recompression. In this article, a thermodynamic model of recompression Brayton was established based gas-cooled fast reactor sensitivity performed. With aim seeking optimal for two-stage, three-stage, four-stage configuration, indicators predicted, respectively. Parameter indicated that thermodynamically optimized result...
Ensuring the high efficiency and stable operation of a supersonic through-flow fan (STFF) in wide range inlet Mach numbers is vital importance. The influence number (M) ranging from 0.3 to 2.36 on aerodynamic performance flow structure STFF cascade studied. results indicate that at design incidence, transonic inflow condition has greater loss, lower static pressure ratio, larger turning than non-transonic condition. evolution shock with increasing as follows: shock-free → passage...
A combined power conversion system, which consists of a supercritical carbon dioxide recompression cycle with an organic Rankine as the bottoming cycle, has broad potential for maritime propulsion applications. However, performance system under off-design condition and operating states compressors wide range load variations different control strategies have not been comprehensively investigated. Therefore, simulation model conditions is established in present study to investigate strategies....
