Comparative study of thermophysical characteristics ofworking fluidsIn this paper, as the study focuses on assessing the aerodynamicperformance of centrifugal turbine used in ORC system, For workingfluid selection, several criteria are used including safety (nonexplosive,non-flammable, and non-toxic), low global warmingpotential (GWP), low ozone depletion potential (ODP) and dry orisentropic fluids. Table 1 shows the selected candidate workingfluids.
