Abstract

This paper presents new wide-ranging correlations for the viscosity of ethene based on critically evaluated experimental data. The viscosity correlation is valid from the triple point to 580 K and up to 195 MPa pressure. The average absolute percentage deviation of the fit for the primary data (including the critical region) is 1 %, with a bias of 0.12 %, while the estimated uncertainty of the correlation in the temperature range from the triple point to 580 K and up to 195 MPa is 3.3 % (at the 95% confidence level). For the dilute gas (pressures up to 0.1 MPa) in the temperature range 296 K to 477 K the uncertainty is 0.5 %. The critical enhancement of the viscosity is less than 1 % outside of the region around the critical point from 279.80 K  T  290.27 K and 140.79 kgm-3    293.08 kgm-3.
