Study on transient ice formation of laminar flow inside externally supercooled rectangular duct
(2000-12-01)
The transient process of solidification of laminar liquid flow (water) submitted to super-cooling was investigated both theoretically and experimentally. In this study an alternative analytical formulation and numerical ...
Size dependence of dynamic fluctuations in liquid and supercooled water
(American Institute of Physics, 2019-04)
We study the evolution of dynamic fluctuations averaged over different space lengths and time scales to characterize spatially and temporally heterogeneous behavior of TIP4P/2005 water in liquid and supercooled states. ...
Viscosity of supercooled aqueous glycerol solutions, validity of the Stokes-Einstein relationship, and implications for cryopreservation
(Academic Press Inc Elsevier Science, 2012-10)
The viscosity of supercooled glycerol aqueous solutions, with glycerol mass fractions between 0.70 and 0.90, have been determined to confirm that the Avramov-Milchev equation describes very well the temperature dependence ...
Enhanced Gruneisen Parameter in Supercooled Water
(Nature Publishing Group, 2019-08-19)
We use the recently-proposed compressible cell Ising-like model to estimate the ratio between thermal expansivity and specific heat (the Gruneisen parameter Gamma(s)) in supercooled water. Near the critical pressure and ...
The water supercooled regime as described by four common water models
(American Institute of Physics, 2013-07)
The temperature scale of simple water models in general does not coincide with the natural one. Therefore, in order to make a meaningful evaluation of different water models, a temperature rescaling is necessary. In this ...
The viscosity of glycerol-water mixtures including the supercooled region
(American Chemical Society, 2011-04)
The dynamic viscosity of water, glycerol, and its mixtures over a wide range of temperatures, including the supercooled region, was calculated resorting to several predictive approaches and compared to published data. The ...
Determining the heterogeneity in time of the dynamics within a slowly relaxing region of a supercooled liquid: Role of sharp relaxation events
(American Physical Society, 2009-08-26)
Supercooled liquids have been shown to be dynamically heterogeneous with different regions of the system presenting dynamics that vary from each other even by orders of magnitude. Computer simulations have confirmed such ...
