Brayton cycle heat engine
WebIn this paper, a recompression S-CO2 Brayton cycle model that considers the finite-temperature difference heat transfer between the heat source and the working fluid, … WebThese devices are called heat engines. Heat engines operate on a cycle and receive heat from a high-temperature source, convert part of this heat to work, and then reject the remaining waste heat to a low-temperature sink during the cycle. A steam power plant is an example of heat engine.
