A test for the Wilson-Levy correlation energy functional
نویسندگان
چکیده
The accuracy of the recently developed correlation energy functional of Wilson and Levy is investigated. The correlation contributions to first ionization potentials of first-row atoms, hydrides and dimers, as well as the contributions to the dissociation energies of neutral and ionic hydrides and dimers are calculated and compared with experimental values. It is found that the functional developed by Wilson and Levy represents a positive step in the way to improve the accuracy of density functional models.

Estimation of Velocity and Detonation Pressure of some High Energy Compounds using Kamlet Method based on Kistiakowski-Wilson Rules
In the present study, the heat of detonation of high energy compounds with CaHbNcOd formula was obtained according to Kistiakowski-Wilson rules. Comparison of these results with experimental date, group additivity method and Kamlet method shows that the values of heat detonation based on the Kistiakowski-Wilson rules are more accurate. In the following, the values of detonation velocity and de...
متن کاملCorrelation of Viscosity of Aqueous Solutions of Alkanolamine Mixtures Based on the Eyring's Theory and Wong-Sandler Mixing Rule
A viscosity model, based on Eyring’s absolute rate theory combined with a cubic PR equation of state and Wong-Sandler mixing rule, has been proposed in order to correlate viscosities of aqueous solutions of alkanolamine mixtures at atmospheric pressure and different temperatures. In the proposed method, the energy and size parameters in studied Equation of State (EoS) have been obtained usi...
متن کاملModeling of liquid–liquid equilibria of aqueous alcohol + salt systems using amodified NRTL
The modified NRTL (m-NRTL) model is used to represent the excess Gibbs free energy of aqueous (alcohol + electrolyte) solutions. In this work, the m-NRTL model previously developed for representation of vapor-liquid equilibria for (polymer + salt + water) systems has been extended to represent liquid-liquid equilibria of (alcohol + salt + water) systems. The proposed extension is a modified of ...
متن کاملEffect of Temperature and Pressure on Correlation Energy in a Triplet State of a Two Electron Spherical Quantum Dot
The combined effect of hydrostatic pressure and temperature on correlation energy in a triplet state of two electron spherical quantum dot with square well potential is computed. The result is presented taking GaAs dot as an example. Our result shows the correlation energies are i)negative in the triplet state contrast to the singlet state ii) it increases with increase in pressure iii)further...
متن کاملStress Analysis and Energy Estimation in Cold-Roll Forming Process
In this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. Geometry of sheet strip is pre-estimated by a shape function. Then longitudinal, transversal and shear strains have been calculated. Using both the Levy-Mises and the Prandtl Reuss equations, and also considering the Bauschinger effect, stress distributions have b...
