The Electrostatic and Fluid Approximations
1998Abstract In contrast to what occurs in vacuum or in ordinary dielectrics, the electric field of a plane wave propagating in a plasma generally has a nonvanishing longitudinal component, Eς = k · E/k ‘F- 0.

Improved fluid superposition approximation
Molecular Physics, 1967An improved superposition approximation is derived for the triplet correlation function of a classical simple fluid in equilibrium. The method of derivation involves the techniques of functional differentation. The associated functional Taylor expansion is taken as far as the triplet term.

Classical ionic fluids in the mean spherical approximation
Inorganica Chimica Acta, 1980The recently obtained analytical solution of the mean spherical approximation has been used to calculate thermodynamic and structural properties of aqueous solutions of asymmetric electrolytes. The same approximation has also been used to calculate structure functions of pure and mixed molten salts.

The Percus–Yevick approximation for quadrupolar molecular fluids
Journal of Physics: Condensed Matter, 2009The Percus-Yevick integral equation theory has been solved to study the equilibrium and structural properties of quadrupolar Gay-Berne fluids. The method used involves an expansion of angle-dependent functions appearing in the integral equations in terms of spherical harmonics and the harmonic coefficients are obtained by an iterative algorithm.

Higher Order Approximation of an Inelastic Fluid Flow
Journal of the Physical Society of Japan, 2003The flow features of inelastic fluids find several industrial applications. Recently, Sacheti et al. have initiated analytical studies to account for the dilatant phenomenon. The authors assumed a linear approximation for the apparent viscosity, and discussed some boundary layer flows.

Approximations in the Theory of Dense Fluids
The Physics of Fluids, 1960A fluid of rigid spheres in equilibrium is considered from a viewpoint which allows the deduced equation of state to reflect very sensitively the accuracy of two approximations to the triplet distribution function. Specifically, these approximations are: (1) the usual Kirkwood superposition scheme, and (2) assumption that the correlation of excess ...

Classical fluids and the superposition approximation
Reports on Progress in Physics, 1968The statistical theory of fluids in equilibrium is developed in that form which is based on the definition of correlation functions and which invokes a superposition closure approximation. Because of the importance of pair interactions between the constituent molecules of a simple fluid, the theory is particularly concerned with the calculation of the ...
