A calculation of the equation of state for NaCl from a Mie-Grlineisen equation was repeated using more accurate values of the zero-pressure compressibility. It was also extended to KCl and CsCl. An analysis of this approach to ...

chemical vapor deposition (cvd) is one of the most popular methods for producing carbon nanotubes (cnts). the growth rate of cnts based on cvd technique is investigated by using a numerical model based on finite volume method. inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal cvd reactor at atmospheric pressure. in thi...

An extension of the transferable potentials for phase equilibria-united atom (TraPPE-UA) force field to acrylate and methacrylate monomers is presented. New parameters were fit to the liquid density, normal boiling point, saturated vapor pressure, and (where experimentally available) critical constants of 1,3-butadiene, isoprene, methyl acrylate, and methyl methacrylate using Gibbs ensemble Mon...

The vapor–liquid coexistence densities, vapor pressure, and heat of vaporization of hydrogen fluoride ~HF! is calculated via Monte Carlo simulation from three intermolecular potential models that are found in the literature. The first is a pure pair potential based solely on ab initio data, the second is a semi-empirical pair potential which uses an ab initio derived surface fitted with dimer s...

Models based on the corresponding-states principle have been extensively used for several equilibrium and transport properties of different pure and mixed fluids. Some limitations, however, have been encountered with regard to its application to long chain or polar molecules. Following previous studies, where it was shown that the corresponding-states principle could be used to predict thermoph...

The leakage process simulation of a Natural Gas Liquid (NGL) storage tank requires the simultaneous solution of the NGL’s pressure, temperature and phase state in the tank and across the leak hole. The methods available in the literature rarely consider the liquid/vapor phase transition of the NGL during such a process. This paper provides a comprehensive pressure-temperature-phase state method...

Mathematical models have been popularly applied to study the compression processes of superheated refrigerant vapor in compressors. As to the case when refrigerant enters a compressor cylinder in the state of liquid and vapor mixture, however, the availability of fundamental studies is very limited. -A mathematical model is presented to simulate the compression processes of two-phase saturated ...

hypoxia is a major concern for human health. multiple new techniques were proposed for tissue oxygenation in different variety of patients.  clark jr. et al. presenting their article titled “fluorovent: a new perfluorocarbon for liquid ventilation”, at a symposium in neonatology, in 1995, described the scientific importance for perfluorocarbons which would be ideally suited for use in liquid ve...

Vapor movement is often an important part in the total water flux in the vadose zone of arid or semiarid regions because the soil moisture is relatively low. The twomajor objectives of this study were to develop a numerical model in the HYDRUS-1D code that (i) solves the coupled equations governing liquid water, water vapor, and heat transport, together with the surface water and energy balance...

Dimethyl amino ethyl azide (DMAZ) is a good replacement for hydrazine group in space programs. This chemical was purified from water (1) + DMAZ (2) mixture in sub-atmospheric distillation column due to thermal sensitivity of DMAZ. For designing of the column, it is necessary to have vapor-liquid equilibrium data. In this article, T-x,y and y-x diagrams were obtain...
