Microturbine one-dimensional design methodology using supercritical carbon dioxide as working fluid

Nowdays, the use of alternative sources of energy has gained much importance due to the reduction of fossil fuel reserves. The supercritical CO
₂
power cycle is being used in applications for power generation with different sources of heat including solar. The main components for a Brayton power cycle are those for turbomachinery group. The purpose of this paper is to present the one-dimensional design development of a turbine for a supercritical power cycle using CO
₂
as working fluid. The procedures here presented take into account the design process of a radial turbine due to the small size found in this component for a supercritical fluid.
