Résumé
[en] Several themes can be tackled in the thematic of organic Rankine cycles. Global system can be optimized as well as each cycle component. In the framework of this master thesis, a key part of an ORC is deeply analyzed: the expander. Indeed, this component is the one directly providing the mechanical power that can be converted in electricity. Many factors can influence its performances which gives to the study a certain complexity.
Several expansion machines exist and the one studied here is a roots expander. Developed first to be a compressor, it is not common to see it used as an expander, which made this work original and stimulating. The roots is a volumetric machine outstanding because of an internal volumetric ratio close to 1. The idea is to develop a semi-empirical model based on an experimental campaign, followed by a serious analysis in term of performances.
