Viscosity measurements and correlations of binary mixtures: 1,1,1,2-tetrafluoroethane (HFC-134a)+tetraethylene glycol dimethylether (TEGDME)

Viscosity measurements on gas expanded liquid systems—Methanol and carbon dioxide

“…The falling-weight viscometer has been used extensively in the past for the determination of viscosities in systems under high pressure [9,14,17,[19][20][21][22][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. The falling-weight viscometer is relatively simple in construction, is easily adaptable for highpressure applications and typically exhibits high repeatability and accuracy.…”

Temperature dependence and chain length effect on density and viscosity of binary mixtures of nitrobenzene and 2-alcohols

“…The theory can be applied to mixtures by employing mixing rules for the three parameters. In the literature, there is no agreement about the best mixing rules to work [16][17][18][19][20][21][22]. The appropriateness of mixing rules is assessed by comparing molecular predictions with experimental data.…”

The high‐pressure viscosity of refrigerant/oil systems

“…Some data exist for this purpose. Monsalvo et al 5,6 measured the viscosity of tetraethylene glycol dimethylether with mole fractions of 0.28, 0.44, 0.63 and 0.88 of R134a and triethylene glycol dimethylether with mole fractions of 0.34 and 0.59 of R134a to pressure of 100 MPa. Comuñas et al 7 measured the viscosity of the same systems to 140 MPa at low mass fractions of oil.…”
