A set of experiments was performed on ethane in order to obtain the thermal diffusivity behavior of this fluid at the critical density over a wide range of the reduced temperature t = T−Tc/Tc where Tc is the critical temperature. The following quantities were measured in the one-phase region: thermal conductivity, turbidity, and decay rate of the spontaneous thermal fluctuations. We associated “classical” measurements of thermophysical properties and optical methods to cover the temperature range of 0.3 K<T−Tc<195 K.
