Measurements of the viscosity of compressed gaseous and liquid methane + ethane mixtures

摘要: The shear viscosity coefficients of three compressed gaseous and liquid nitrogen + methane mixtures have been measured at temperatures between 100 300 K pressures to about 30 MPa (4350 psia) with a piezoelectric quartz crystal viscometer. precision the measurements ranges from 0.5% high densities 1% low densities. estimated experimental error 2% 4% near critical density supercritical temperature. compared an extended corresponding states model, previously proposed for calculating viscosities fluid mixtures. Differences calculated are discussed.
