OPTIMUM WORKING FLUIDS FOR AUTOMOTIVE RANKINE ENGINES. VOLUME II. TECHNICAL SECTION

The objective of the work was to determine the best working fluids available for the automotive Rankine engine application. Specific guidelines were established for the fluid screening process. The details of the screening and testing procedures are presented. As a result of the various criterion-guided experimental and computational studies, two final candidate fluids were identified: RC-1: A 60/40 mole percent mixture of pentafluorobenzene/hexafluorobenzene; RC-2: A 65/35 mole percent mixture of water/2-methylpyridine. Both fluids are liquid to -40F and meet critical performance criteria for both reciprocating and turbine engines, although neither completely satisfies all requirements and criteria. The experimental program to characterize them is presented.
