Figure 14

Thermal diffusivity of CO2 measured with a interferometry of the fluid sample below a transient heated plate by Becker and Grigull52 along isotherms near the critical point. The isotherms are designated by symbols: △, 298.147 K; ◇, 304.362 K; □, 305.228 K, ○, 307.958 K. The dashed lines show the calculated thermal diffusivity with the present correlation with the Span and Wagner114 equation of state and the solid lines show the calculated thermal diffusivity with the present correlation with the Albright et al. 127 scaled equation of state. The critical density is shown with the dot–dashed line.
