On the algorithm to perform Monte Carlo simulations in cells with constant volume and variable shape

open access: yesCondensed Matter Physics, 2022
In simulations of crystals, unlike liquids or gases, it may happen that the properties of the studied system depend not only on the volume of the simulation cell but also on its shape.

An internal swelling factor model to examine the influence of permeability anisotropy on coalbed methane extraction

open access: yesEnergy Science & Engineering, 2020
Owing to the characteristics of coal reservoirs, the gas flow capacity and permeability exhibit strong anisotropy. The anisotropy in terms of the magnitude, which corresponds to the permeability in the horizontal direction being several orders of ...

Analysis of the chemical equilibrium of combustion at constant volume [PDF]

open access: yesINCAS Bulletin, 2014
Determining the composition of a mixture of combustion gases at a given temperature is based on chemical equilibrium, when the equilibrium constants are calculated on the assumption of constant pressure and temperature.

Volume Polynomials for Some Polyhedra in Spaces of Constant Curvature

open access: yesМоделирование и анализ информационных систем, 2015
It is known that for each simplicial polyhedron P in 3-space there exists a monic polynomial Q depending on the combinatorial structure of P and the lengths of its edges only such that the volume of the polyhedron P as well as one of any polyhedron ...

Simultaneous ultrafiltration and diafiltration [PDF]

open access: yesHemijska Industrija, 2002
A model with simultaneous ultrafiltration and diafiltration, which includes the rejection coefficients, is presented in this study. Adding a diafiltration solution at a constant, lower rate than the filtrate rate results in a constant decrease of the ...
