Evaluation of transient characteristics of medium temperature solar thermal systems utilizing thermal stratification

A review of solar-driven organic Rankine cycles: Recent challenges and future outlook

“…They found that the system efficiency was about 15% while the ORC efficiency was as high as 26%. Majumdar et al [116] investigated a novel solar-ORC system using a dynamic moving boundary model that was developed for medium-temperature collectors. A time-dependent model was developed for the variation of heat transfer fluid temperature.…”
