Helium fluidthermodynamic propertyab initio potentialmolecular dynamicsuncertaintyThe molecular dynamics simulation method is used to study the internal energy, pressure, isochoric heat capacity, and sound speed of helium based on the state-of-the-art ab initio potentials. The simulations cover a wide ...

HEPROP is a set of subprograms used to calculate the thermophysical properties of helium. The thermodynamic properties are derived from the equation of state developed by McCarty, which is valid from about 2K to 1700K, and up to about 100 MPa. By analytical differentiation and integration, press...
In order to explain certain properties of thin helium films, Ziman has proposed an ideal gas model in which the bulk liquid is treated as a collection of independent, Bose–Einstein assemblies each a few hundred angstroms in extent. In this paper, an extensive numerical study is made of the...
Besides, the mechanism of fluid flow propagation (i.e., pervasive versus channelized10,11,12) and the fact of Phanerozoic secular cooling of Earth mantle13 also hinder the efficiency of volatile mobilization beneath the subarc, further making the feeding of subducted volatile into the mantle ...
In contrast to the case of liquid helium, where the depleted fraction is large (of order 93% of the fluid36,37,38) due to the strong interparticle interactions, the depletion is generally very small (less than 1%7,12) in weakly-interacting dilute gases. The intimately related thermodynamic ...
Henceforth the term porosity refers to the total porosity measured using a helium as the pore fluid. All samples were dried in a vacuum oven at 40 °C for at least 48 h prior to experimentation at ambient temperature and humidity. A lubricating wax was applied to both ends of the samples...
The purpose of this report is to summarize some of the contributions that have been made by this laboratory to thermophysical properties data research on the monatomic and diatomic gases (helium, hydrogen, nitrogen, oxygen, fluorine, and argon) and to discuss the ongoing research on the ...
The flow of light can exhibit hydrodynamic-like properties which are characteristic of the collective behavior of quantum many-body systems (e.g., liquid helium or ultracold atomic gases1), hence showing properties which are characteristics of superfluids rather than conventional classical fluids (wate...
of 1190 W. Helium (0.9 l/min) and Ar (0.95 l/min) were used as carrier gases. Argon was used as plasma (14.9 l/min) and auxiliary gas (0.9 l/min). A single spot ablation pattern with a frequency of 20 Hz and a fluence of 4.04 J/cm2was used. The total analysis time for ...
