Abstract
This paper reports experimental results for the viscosity of gaseous mixtures of methoxymethane + nitrogen. The measurements were carried out with an oscillating-disk viscometer of the Maxwell type at temperatures from (298.15 to 423.15) K and at pressures up to 4.97 MPa. The viscosity at 0.1 MPa was found to be correlated with a maximum deviation of 1.7 % and average deviation of 0.9 % by the Chapman−Enskog equation. An empirical equation was obtained for the viscosity as a function of composition, temperature, and density. This equation reproduced the observed viscosity with a maximum deviation of 3.8 % and an averaged deviation of 0.7 %.
