Non-Newtonian effects in silicate liquids and crystal bearing melts: Implication for magma dynamics

Viscosity of hydrous rhyolitic melts inferred from kinetic experiments, and a new viscosity model

Viscosity of hydrous silicate melts is essential in modeling the dynamics of magma transport and volcanic eruptions. Numerous experimental measurements of viscosity, as well as viscosity models, have been published. For general melt compositions, the classic models of either Bottinga and Weill (1972) or Shaw (1972) are still used, not because they are reliable, but because of the extreme diffic...

A new approach to the equation of state of silicate melts: An application of the theory of hard sphere mixtures

A comparison of compressional properties of silicate solids, glasses, and liquids reveals the following fundamental differences: (1) Liquids have much smaller bulk moduli than solids and glasses and the bulk moduli of various silicate melts have a narrow range of values; (2) Liquids do not follow the Birch’s law of corresponding state as opposed to solids and glasses; (3) The Grüneisen paramete...

An Analytical Equation of State Extended to Copolymers

calculate some thermodynamic properties of molten polymers including specific volume and isothermal compressibility (S.M. Hoseini, Physical Chemistry & Electrochemistry, 2 (2014) 56-65). This work extended that EOS to predict the volumetric properties of some molten ethylene copolymers including ethylene/1-octene, ethylene/1-butene (xethylene equal to 0.8543 and 0.563), ethylene/propene. The ab...
