A literature research on feasible application of mixed working fluid in flexible distributed energy system

This paper provides a guided technological tour on the proposed concept--flexible DES (FDES), through a literature research, in terms of features, definition, and capacity adjustment measures. In particular, one kind of FDES featured by the application of mixed working fluid (MWF) is highlighted as the main object in this paper through a summary on separation and mixing mechanism of MWF. An overview about the typical technologies to access such mechanisms, including T junction, ejector, cyclone and distillation, is presented to demonstrate advances and application potential of FDES. Finally, two representative cases from publications are briefly presented and discussed for existing configurations of FDES and possible application of separation and mixing technologies. The literature works in this paper proved a promising application prospect of the new concept FDES due to its significant performance improvement and flexible adjustment function.
