Extension of the dielectric breakdown model for simulation of viscous fingering at finite viscosity ratios [PDF]
Immiscible displacement of viscous oil by water in a petroleum reservoir is often hydrodynamically unstable. Due to similarities between the physics of dielectric breakdown and immiscible flow in porous media, we extend the existing dielectric breakdown ...

Thermophysical properties of a Cu46Zr42Al7Y5 bulk metallic glass-forming liquid [PDF]
The thermophysical properties, including the specific volume V, the surface tension sigma, and the viscosity eta, of a Cu46Zr42Al7Y5 bulk metallic glass in the molten state were investigated using a containerless high-temperature high-vacuum ...

Comment on the power law in rheological equations [PDF]
In conformity with the principle of shear reversal, it is proposed that the power law index in the Cross equation relating steady state viscosity to shear rate in semisolid alloy slurries should have a value of 4/3, which is independent of alloy system ...

A Viscosity Method for the Min-Max Construction of Closed Geodesics [PDF]
We present a viscosity approach to the min-max construction of closed geodesics on compact Riemannian manifolds of arbitrary dimension. We also construct counter-examples in dimension $1$ and $2$ to the $\varepsilon$-regularity in the convergence ...

Probing equilibrium glass flow up to exapoise viscosities [PDF]
Glasses are out-of-equilibrium systems aging under the crystallization threat. During ordinary glass formation, the atomic diffusion slows down rendering its experimental investigation impractically long, to the extent that a timescale divergence is ...
