In a Rankine cycle, high-pressure liquid water (1) enters a boiler where it is heated to saturation temperature (2), vaporized, and superheated (3). The superheated steam is fed to a turbine, where it

Computer-based simulations of Organic Rankine Cycles (ORC) have been extensively used in the last two decades to predict the behaviour of existing plants or already in the design phase. For time-varying heat sources, researchers typically rely on either quasi-steady state or dynamic simulations.
Utilizing organic Rankine cycle (ORC) devices to generate power from renewable energy and low-quality heat sources has gained more attention recently. Waste heat recovery has been effectively applied by ORC. Unlike the steam power cycle, ORCs use hydrocarbons, refrigerants, silicone oil, solvents, or other organic compounds.
Abstract: Recently, there has been a notable increase in focus on the organic Rankine cycle (ORC) progress. The system has remarkable abilities in the application of low-temperature and sustainable energy. This study examines the energy assessment of a hermetic scroll expander in an ORC. The chosen organic working fluid was R134a.
One of the important factors to be considered in an organic Rankine cycle system is the type of working fluid. The working fluids must be selected carefully as they hold an important role in the system efficiency, cycle operation and its impact to the environment. Apart from the working fluid, system configuration must also be taken into account.
