Simple calculation of the pair distribution function for a moderately dense hard-sphere fluid
Chemical Physics Letters, 1971Abstract The pair distribution function and equation of state of a hard-sphere fluid are calculated for several modifications of the Percus-Yevick (PY) theory by means of a perturbation calculation in which the zeroth-order term is the PY result.

Numerical analysis of flow distribution inside a compact ceramic high temperature heat exchanger and chemical decomposer (thereafter, heat exchanger), which will be used for hydrogen production, wherein the sulfur iodine thermochemical cycle is performed. To validate the numerical model, experimental investigation of the heat exchanger is accomplished.

To visualize irrigation fluid flow and calculate its velocity distribution in the anterior chamber during phacoemulsification by particle image velocimetry.Porcine eyes were fixed in a glass chamber filled with balanced salt solution. An ultrasound handpiece was fixed to the glass chamber, and its tip was inserted into the anterior chamber through a ...

Calculation of Initial Fluid Distributions in Oil Reservoirs
Transactions of the AIME, 1949Abstract It is pointed out that the application of capillary pressure curves obtainedby drainage or desaturation processes to the calculation of the fluiddistribution in interphase transition zones involves a number of difficulties;namely:the development of very low nonwetting phase saturations appears tobe in ...

Physical Review A, 1984
We report the first molecular-dynamic calculation of the quantum corrections of the pair-distribution function for a Lennard-Jones fluid. The method is based on the Wigner-Kirkwood expansion and is useful for "almost classical" many-body systems.

Abstract A method for calculating the entropy and the chemical potential of fluids and solids from the radial free-space distribution function (RFSDF) is proposed. The free volume is obtained from the RFSDF by eliminating the arbitrary definition of a cell and the imposition of a cut-off distance that were used in the theory of the previous paper ...

Using the Lennard-Jones 6–12 potential and the Percus—Yevick equations, the radial distribution functions for a number of binary mixtures have been calculated as a function of the Lennard-Jones parameters and the thermodynamic state. These are compared with one-component distribution functions and with those for binary hard-sphere fluids. The effect of

Abstract Temperature of the oil used as the Heat Transfer Fluid (HTF) in power supporting natural gas boilers is the most critical factor due to the proximity of its degradation point to the working regime. Detailed predictions through Computational Fluid Dynamics (CFD) calculations are too expensive in both time and resources.

Journal of Magnetism and Magnetic Materials, 1993
Abstract It has been found experimentally that the magnetization curve of a magnetic fluid (MF) depends on the time of measurement. This phenomenon can be explained by the effect of the aggregation process. A new method of measurement that does not affect the dispersive composition of an MF is presented.
