[en] This study investigates the possibility to associate a scroll expander to a heat recovery Rankine cycle, working with water. In view to develop such a scroll expander, three scroll compressors are adapted to be run in expander mode. The three tested expanders are fed with water steam and air. Two of them need to be lubricated. The third expander is also fed with a binary mixture of water and propylene glycol. A model of scroll expander is proposed and validated.
