Calculation of the compressibilities of hard-sphere fluids from the radial free space distribution function and its application to sound velocity

The Journal of Chemical Physics, 2000
The relation between the compressibility and the radial free space distribution function (RFSDF) has been derived. This method for calculating the compressibility employing RFSDF is useful because the compressibility of any system is obtainable in a single Monte Carlo simulation without obtaining the equation of state.

The Method of Hydraulic Calculation of a Heat Exchange Panel of a Solar Water-Heating Collector of a Tube–Tube Type with a Given Nonuniform Distribution of Fluid Flow Along Lifting Pipes

Applied Solar Energy, 2020
The purpose of this work is to develop a method for the hydraulic calculation of a heat exchange panel of a solar tube collector of a tube type with a given nonuniform distribution of fluid flow under conditions of forced circulation. On the basis of previously obtained design dependencies, a method of hydraulic calculation of a heat exchange panel of ...

The calculation of wall and fluid temperatures for the incompressible turbulent boundary layer, with arbitrary distribution of wall heat flux

International Journal of Heat and Mass Transfer, 1962
Abstract Numerical solution of the partial differential equation for heat transfer in the incompressible turbulent boundary layer has been obtained for uniform ( q w ρC p u i )/√( c f 2 ) and for Prandtl numbers 0–7, 1 and 7.

Measurement of 2D-temperature distributions in a pervaporation membrane module using ultrasonic computer tomography and comparison with computational fluid dynamics calculations

Journal of Membrane Science, 2002
Temperature polarization effects can considerably limit the overall performance of pervaporation modules. This study shows the measurement of temperatures in a pervaporation membrane module using ultrasonic computer tomography (U-CT). With this technique complete 2D-temperature distributions that occur in the module can be measured within seconds ...

A test-particle method for the calculation of the three-particle distribution function of the hard-sphere fluid: density functional theory and simulation

Journal of Physics: Condensed Matter, 1999
The three-particle distribution function g(3) of the homogeneous hard-sphere fluid is studied by means of the test-particle method of Percus. We consider an inhomogeneous situation in which the position of two particles is fixed and the inhomogeneous density profile that arises is related to g(3).

On the calculation of the single-particle momentum and energy distributions for a hard-core fluid in the microcanonical molecular dynamics ensemble

Physica A: Statistical Mechanics and its Applications, 1996
Abstract The microcanonical molecular dynamics ensemble describes a system with a fixed number of particles in a given volume and with constant total energy and total linear momentum. The primary phase integrals of this ensemble for a hard-core fluid are derived by using geometrical arguments.

Calculation of the pressure distribution over the surface of a vibrating solid in a semi-incompressible fluid by means of the finite element method1

International Shipbuilding Progress, 1978
This paper presents the theoretical basis used to develop, in AESA, a computer program to solve the direct calculation of the actuating pressure forces on a vibrating solid inside a fluid. The problem is solved both in the case of slightly compressible and incompressible fluids having reached, in the first case, a completely original solution.

Effects of thyrotropin, acetazolamide, 4-acetamido-4'-isothiocyanostilbene-2,2'-disulfonic acid, perchlorate, ouabain and furosemide on pH and HCO3- concentrations in cells and luminal fluid of turtle thyroid as calculated from the distribution of [14C]dimethyloxazolidine-2,4-dione.

The Journal of Pharmacology and Experimental Therapeutics, 1983
[14C]Dimethyloxazolidine-2,4-dione was used to determine the pH and bicarbonate concentration ([HCO3-]) in follicular cells and luminal fluid (LF) of turtle thyroids. Values of cellular and luminal pH and [HCO3-] were derived from the steady-state [14C]dimethyloxazolidine-2,4-dione values in whole gland and in the follicular LF sampled by micropipettes

Calculated distribution of various inorganic phosphate constituents in body fluids, based on the principles of complex equilibria.

Clinical physiology and biochemistry, 1985
The distribution of inorganic phosphate ions in body fluids is calculated by equilibrium studies. Equations of partial mol fractions of each complex species are calculated with known stability constants, measured pH and electrolyte concentrations. We present these results in serum and urine in health, and in some diseases, with characteristic pH values
