In this paper, working fluids are modelled by the Redlich-Kwong equation of state. It is demonstrated that a limiting isochoric heat capacity might exist between dry and wet fluids. With the Redlich-Kwong equation of state, this limit can be predicted with good accuracy for several fluids, including alkanes.<\/jats:p>","DOI":"10.3390\/e20020093","type":"journal-article","created":{"date-parts":[[2018,1,30]],"date-time":"2018-01-30T05:02:34Z","timestamp":1517288554000},"page":"93","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Prediction of the ORC Working Fluid\u2019s Temperature-Entropy Saturation Boundary Using Redlich-Kwong Equation of State"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7966-4218","authenticated-orcid":false,"given":"Axel","family":"Groniewsky","sequence":"first","affiliation":[{"name":"Department of Energy Engineering, Budapest University of Technology and Economics, Muegyetem rkp. 3, H-1111 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Attila","family":"Imre","sequence":"additional","affiliation":[{"name":"Department of Energy Engineering, Budapest University of Technology and Economics, Muegyetem rkp. 3, H-1111 Budapest, Hungary"},{"name":"MTA Centre for Energy Research, Department of Thermohydraulics, P.O.
