Dynamic van der Waals theory.
We present a dynamic van der Waals theory starting with entropy and energy functional with gradient contributions. The resultant hydrodynamic equations contain the stress arising from the density gradient. It provides a general scheme of two-phase hydrodynamics involving the gas-liquid transition in nonuniform temperature. Some complex hydrodynamic processes with evaporation and condensation ar...
متن کاملA Modified van der Waals Mixture Theory for Associating Fluids: Application to Ternary Aqueous Mixtures
In this study a simple and general chemical association theory is introduced. The concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. The theory is applied to derive the distribution function of associated species. As a severe test the application of presented theory to the van der Waals mixture model is introduced in order to p...
متن کاملThe van der Waals interaction
The interaction between charged particles via the Coulomb interaction is one of the most important features in physics and is familiar to any student of the subject. The way in which electrons and protons bind to form the hydrogen atom is also well known and is a staple of any quantum mechanics course. However, less familiar is the interaction between such bound systems at separation R, which i...
متن کاملvan der Waals interactions in density-functional theory.
We present a new scheme to include the van der Waals (vdW) interactions in approximated Density Functional Theory (DFT) by combining the quantum harmonic oscillator model with the maximally localized Wannier function technique. With respect to the recently developed DFT/vdW-WF2 method, also based on Wannier Functions, the new approach is more general, being no longer restricted to the case of w...
متن کاملQuantum Field Theory of the Van Der Waals Friction
The van der Waals friction between two semi-infinite solids, a small neutral particle and semi-infinite solid is reconsidered on the basis of thermal quantum field theory in Matsubara formulation. The friction calculated in this approach is in agreement with the friction calculated in the framework of dynamical modification of the Lifshitz theory with use of the fluctuation-dissipation theorem....
