Reference Correlations of the Viscosity and Thermal Conductivity of 1-Hexene from the Triple Point to High Temperatures and Pressures

Abstract

This paper presents new wide-ranging correlations for the viscosity and thermal conductivity of 1-hexene based on critically evaluated experimental data. The viscosity correlation is valid from the triple point to 580 K and up to 245 MPa pressure, while the thermal conductivity is valid from the triple point to 620 K and 200 MPa pressure. Both correlations are designed to be used with a recently published equation of state that extends from the triple point to 535 K, at pressures up to 245 MPa. The estimated uncertainty (at a 95 % confidence level) for the viscosity is 2 % for the low-density gas (pressures below 0.5 MPa), and 4.8 % over the rest of the range of application. For thermal conductivity, the expanded uncertainty is estimated to be 3 % for the low-density gas and 4 % over the rest of the range.
