The Liquidus Temperature for Methanol-Water Mixtures at High Pressure and Low Temperature, with Application to Titan
A. J. Dougherty, Z. T. Bartholet, R. J. Chumsky +3
Methanol is a potentially important impurity in subsurface oceans on Titan and Enceladus. We report measurements of the freezing of methanol-water samples at pressures up to 350~MP…
Nonsymmetric multigrid preconditioning for conjugate gradient methods
Henricus Bouwmeester, Andrew Dougherty, Andrew V. Knyazev
We numerically analyze the possibility of turning off post-smoothing (relaxation) in geometric multigrid when used as a preconditioner in conjugate gradient linear and eigenvalue s…
The initial growth of sidebranches in ammonium chloride dendrites
Andrew Dougherty
We report measurements for the initial stages of sidebranching during the dendritic growth of ammonium chloride from supersaturated aqueous solution. The earliest sidebranches are…
Measurement of the Capillary Length for the Dendritic Growth of Ammonium Chloride
Andrew Dougherty
We report the results of a new method of measuring the capillary length for the dendritic crystal growth of non-faceted materials. This method uses a nearly spherical crystal held…
The Transient Growth of Ammonium Chloride Dendrites
Andrew Dougherty, Thomas Nunnally
We report measurements of the initial growth and subsequent transient response of dendritic crystals of ammonium chloride grown from supersaturated aqueous solution. Starting from…
Shape of ammonium chloride dendrite tips at small supersaturation
Andrew Dougherty, Mayank Lahiri
We report detailed shape measurements of the tips of three-dimensional ammonium chloride dendrites grown from supersaturated aqueous solution. For growth at small supersaturation,…
Driven interfaces in disordered media: determination of universality classes from experimental data
Reka Albert, Albert-Laszlo Barabasi, Nathan Carle +1
While there have been important theoretical advances in understanding the universality classes of interfaces moving in porous media, the developed tools cannot be directly applied…
