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 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 کاملThermodynamic performance of new thermofluidic feed pumps for Organic Rankine Cycle applications
This study develops thermofluidic pump technology that is powered by heat, rather than by electrical or mechanical power. The objective is to improve the performance of heat-recovery by Organic Rankine Cycles, by using a recently-proposed thermofluidic pump. The thermofluidic pump promises low-cost, high-reliability, and, since it does not consume any of the power produced by the expander, impr...
