Description

This paper reports the physical properties of PFC(Perfluorocarbon. equi-mass mixture of C8H18 and C8F16O here). The PFC is a good candidate for liquid-liquid direct contact heat exchange beccause it is inert chemically and insoluble to water. ln the present study, five thermal properties of PFC(density, kinematic viscosity, interfacial tension with water, specific heat, and thermal conductivity) were measured by using various measuring methods in the temperature range from 273.15K to 323.15K. From the data obtained, the thermal properties for PFC were regressed as a function of temperature. ln addition, thermal diffusivity and Prandtl number of PFC were expressed as a function of temperature.
