Preliminary Design and Simulation of a Turbo Expander for Small Rated Power Organic Rankine Cycle (ORC)
Nowadays, the Organic Rankine Cycle (ORC) system, which operates with organic fluids, is one of the leading technologies for “waste energy recovery”. It works as a conventional Rankine Cycle but, as mentioned, instead of steam/water, an organic fluid is used. This change allows it to convert low temperature heat into electric energy where required. Large numbers of studies have been carried out...
متن کاملComparison of Organic Rankine Cycle Systems under Varying Conditions Using Turbine and Twin-Screw Expanders
A multi-variable optimization program has been developed to investigate the performance of Organic Rankine Cycles (ORCs) for low temperature heat recovery applications using both turbine and twin-screw expanders when account is taken of performance variation due to changes in ambient conditions. The cycle simulation contains thermodynamic models of both types of expander. In the case of the twi...
متن کاملModeling and simulation of small-scale Organic Rankine Cycle
The Organic Rankine Cycle (ORC) heat engine constitutes a very promising technology to recover waste heat (for instance from industry or from internal combustion engines) but also to exploit renewable energy sources (such as solar, biomass or geothermal energy). This seminar will emphasize how modeling and simulation tools could be used during the design stage of an ORC system in order to best ...
متن کاملSelection and Conversion of Turbocharger as Turbo-expander for Organic Rankine Cycle (orc)
Turbo-expander is the most crucial and expensive component in Organic Rankine Cycle (ORC) power generation systems. The turbine engineering, design and research development process for ORC system is costly, time-consuming, and difficult for new-entrants in the ORC field. This paper investigates the re-design and retrofit of an off-the-shelf turbocharger for use in a 1 kW ORC system. The expande...
متن کاملExperimental and Thermoeconomic Analysis of Small-Scale Solar Organic Rankine Cycle (SORC) System
A small-scale solar organic Rankine cycle (ORC) is a promising renewable energy-driven power generation technology that can be used in the rural areas of developing countries. A prototype was developed and tested for its performance characteristics under a range of solar source temperatures. The solar ORC system power output was calculated based on the thermal and solar collector efficiency. Th...
