摘要：

In response to the growing interest in supercritical carbon dioxide (S-CO2) power cycle technology because of its potential enhancement in compactness and efficiency, the S-CO2 cycles have been studied intensively in the fields of nuclear power, concentrated solar power (CSP), and fossil fuel power generation. Despite this interest, there are relatively few studies on waste heat recovery applications. In this study, the S-CO2 cycle that has a split flow with preheating was modeled and simulated. The variation in the power was investigated with respect to the changes in the value of a design parameter. Under the simulation conditions considered in this study, it was confirmed that the design parameter has an optimal value that can maximize the power in the S-CO2 power cycle that has a split flow with preheating. © 2015 The Korean Society of Mechanical Engineers.
