Comment on “Symmetric Liquid-liquid Interface with a Nonzero Spontaneous Curvature”

Comment on "Spontaneous liquid-liquid phase separation of water".

Yagasaki et al. [Phys. Rev. E 89, 020301 (2014)] present results from a molecular dynamics trajectory illustrating coarsening of ice, which they interpret as evidence of transient coexistence between two distinct supercooled phases of liquid water. We point out that neither two distinct liquids nor criticality are demonstrated in this simulation study. Instead, the illustrated trajectory is con...

Axially Symmetric Vibrations of a Liquid-Filled Poroelastic Thin Cylinder Saturated with Two Immiscible Liquids Surrounded by a Liquid

This paper studies axially symmetric vibrations of a liquid-filled poroelastic thin cylinder saturated with two immiscible liquids of infinite extent that is surrounded by an inviscid elastic liquid. By considering the stress free boundaries, the frequency equation is obtained. Particular case, namely, liquid-filled poroelastic cylinder saturated with single liquid is discussed.  When the waven...

A Study on Liquid-liquid Mixing in a Stirred Tank with a 6-Blade Rushton Turbine

The turbulent flow field generated in a baffled stirred tank was computed by large eddy simulation (LED) and the flow field was developed using the Sliding Mesh (SM) approach. In this CFD study, mixing times and power number have been determined for a vessel agitated by a 6-blade Rushton turbine. The predicted results were compared with the published experimental data. The satisfactory results ...

Orientation of Symmetric Bodies Falling in a Second-Order Liquid at Nonzero Reynolds Number

We study the steady translational fall of a homogeneous body of revolution around an axis s, with foreand-aft symmetry, in a second-order liquid at nonzero Reynolds (i‚ ) and Weissenberg (G‚ ) numbers. We show that, at first order in these parameters, only two orientations are allowed, namely, those with s either parallel or perpendicular to the direction of the gravity /. In both cases the tra...
