Design and simulation of supercritical carbon dioxide recompression Brayton cycles with regenerators for recuperation
The supercritical carbon dioxide recompression Brayton cycle is being considered for CSP applications due to its potential for lower cost and higher efficiency relative to steam Rankine cycles, but achieving high efficiency requires large, expensive recuperators. Regenerators may provide cost and performance advantages over traditional heat exchanger technology. A regenerator is a periodic heat exchanger in which the transfer of heat from the hot to cold fluid is temporally decoupled via a thermal energy storage media, such as a packed bed of spheres inside an insulated pressure vessel. Valves ...
