Abstract (en)

A power generating system employs a Rankine cycle system that is coupled to multiple heat sources (106, 108). The Rankine cycle system includes a customized working fluid that comprises a mixture of a plurality of constituent fluids, the selection of which gives the mixture a working fluid profile. In one embodiment, the working fluid profile includes a temperature glide portion selected and optimized based on operating conditions of the heat sources, wherein the temperature glide portion includes a constituent phase point at which one of the constituent fluids undergoes a phase change before the other constituent fluids of the mixture.
