Multicomponent Working Fluids For Organic Rankine Cycles (ORCs)

Energy, 1998
We have evaluated the merits of organic-fluid mixtures as working media for Rankine power cycles. Non-isothermal phase change both at high and low temperature represents the main advantage with respect to pure fluids. StanMix, a computer code using the Wong and Sandler (WS) mixing rules, integrated into a commercial package, is employed for cycle ...

Developments on Small-Scale Organic Rankine Cycle (ORC) Systems

Journal of Fundamentals of Renewable Energy and Applications, 2016
The organic Rankine cycle (ORC) technology is perhaps the most suitable technology for heat recovery applications from sources of low temperature (even lower than 100°C) [1], while it can also be used for temperatures up to about 300°C with a variety of scale (from the kW up to the MW scale).

Exergetic optimization of double stage Organic Rankine Cycle (ORC)

Energy, 2018
Abstract The present work focuses on the exergetic optimization of double stage Organic Rankine Cycle (DS ORC) for waste heat recovery. A model of a DS ORC, consisting of a high temperature (HT) stage serially connected to a low temperature (LT) stage is developed, while different combinations of working fluids with variable critical temperatures are

Energetic optimization of regenerative Organic Rankine Cycle (ORC) configurations

Energy Conversion and Management, 2018
Abstract The present study focuses on the energetic optimization of regenerative Organic Rankine Cycle (ORC) configurations. More specifically, three regenerative ORCs are examined. The first includes an open preheater, in which the bleed stream is mixed with the working fluid exiting the pump of the cycle (O-ORC).

Internal Combustion Engine (ICE) bottoming with Organic Rankine Cycles (ORCs)

Energy, 2010
Abstract This paper describes a specific thermodynamic analysis in order to efficiently match a vapour cycle to that of a stationary Internal Combustion Engine (ICE). Three different working fluids are considered to represent the main classes of fluids, with reference to the shape of the vapour lines in the T–s diagram: overhanging, nearly ...

Comparation on R245fa, R1233zd, R141b for Organic Rankine Cycle (ORC)

2018 Conference on Power Engineering and Renewable Energy (ICPERE), 2018
Indonesia’s largest source of power generation comes from steam power plant. This paper discusses Organic Rankine Cycle (ORC) as an alternative for steam power plant system design. ORC has Rankine Cycle as a cycle but use organic working fluid as a replacement for water. Majority, ORC’s manufacturer use R245fa as working fluid.

Alternative approach in performance analysis of organic rankine cycle (ORC)

Environmental Progress & Sustainable Energy, 2018
In this study, artificial neural networks (ANNs) and adaptive neuro‐fuzzy (ANFIS) have been used for performance analysis of organic rankine cycle (ORC) using refrigerants R123, R125, R227, R365mfc, SES36. It is well known that the steam generator temperature, condenser temperature, subcooling temperature, and superheating temperature affect the ...

Review of organic Rankine cycle (ORC) architectures for waste heat recovery

Renewable and Sustainable Energy Reviews, 2015
Abstract The organic Rankine cycle (ORC) is commonly accepted as a viable technology to convert low temperature heat into electricity. Furthermore, ORCs are designed for unmanned operation with little maintenance. Because of these excellent characteristics, several ORC waste heat recovery plants are already in operation.
