The article discusses various types of expanders used in the organic Rankine cycle systems
to turn thermal energy into electrical energy. In addition to basic information on scroll, screw …

Abstract The Organic Rankine Cycle (ORC) is a technology commonly used for low-grade
thermal energy conversion in electricity. This technology is mature for large power scale and …

Small and micro energy sources are becoming increasingly important in the current
environmental conditions. Especially, the production of electricity and heat in so-called …

The working fluid selection is one of the most important issues faced when designing
Organic Rankine Cycle (ORC) systems. The choice of working fluid is dictated by different …

This paper presents the results related to the performance of two expanders running in
parallel in a regenerative ORC system. Scroll expanders with nominal outputs of 1 kW e …

The paper presents an experimental evaluation of the efficiency of a small-scale low-
temperature organic Rankine cycle (ORC) as an mCHP (micro Combined Heat and Power) …

Partial admission is often used in small ORC turbines due to a relatively low value of specific
speed parameter. The paper aims at elaboration of new modeling and design approach for …

The paper presents an analysis of a turbine based micro ORC system for a domestic
biomass boiler. The assumed nominal boiler capacity is in the range between 15 kW and 20 …

This paper reviews the applications of the multi-vane expanders in ORC (organic Rankine
cycle) systems. The operating principle and design of the ORC systems are addressed in the …

Advances in the development of analysis and design methods for fluid-flow machines have
enabled both their multi-criteria optimisation and miniaturisation. To decrease the size of …
