Integral Mass Balance (IMB) Method for Measuring Multicomponent Gas Adsorption Equilibria in Nanoporous Materials [PDF]

Industrial & Engineering Chemistry Research, 2020
Multicomponent gas adsorption equilibria must be determined in order to assess the performance of an adsorbent for a particular gas separation and for process design. The experimental techniques commonly used for this purpose, however, are time-consuming and typically require large samples.

Reserve evaluation of high pressure and ultra-high pressure reservoirs with power function material balance method

Natural Gas Industry B, 2019
It is difficult to determine the effective reservoir rock compressibility, aquifer volume and water influx of high pressure and ultra-high pressure gas reservoirs, so when the traditional apparent reservoir pressure and cumulative gas production curve ...

Stabilized material point methods for coupled large deformation and fluid flow in porous materials

, 2019
The material point method (MPM) has been increasingly used for the simulation of large deformation processes in fluid-infiltrated porous materials. For undrained poromechanical problems, however, standard MPMs are numerically unstable because they use ...

A Hybrid Godunov Method for Radiation Hydrodynamics

, 2010
From a mathematical perspective, radiation hydrodynamics can be thought of as a system of hyperbolic balance laws with dual multiscale behavior (multiscale behavior associated with the hyperbolic wave speeds as well as multiscale behavior associated with

The missing stress-geometry equation in granular media

, 2001
The simplest solvable problem of stress transmission through a static granular material is when the grains are perfectly rigid and have an average coordination number of $\bar{z}=d+1$.
