Transport Properties ofn-Dodecane

We have surveyed literature data and developed correlations for the viscosity and thermal conductivity of n -dodecane that are valid over a wide range of fluid states. The new correlations are applicable from the triple point (263.59 K) to 800 K, and at pressures up to 200 MPa. The viscosity correlation has an estimated uncertainty of 0.5% along the saturation boundary in the liquid phase, 3% in the compressed liquid region, and 3% in the vapor (where the uncertainties can be considered as estimates of a combined expanded uncertainty with a coverage factor of 2). The thermal conductivity correlation has an estimated uncertainty of 4% along the liquid saturation boundary and in the compressed liquid, and ∼5% in the vapor region.
