Evaluation of gas sorption-induced internal swelling in coal
Fuel, 2015Abstract Gas sorption plays an important role in permeability evolution and gas flow in coal. Many efforts have been made to evaluate the effect of gas sorption on permeability. For example, the total gas sorption matrix swelling is divided in to two pars, one acts on cleat (internal swelling) and the other contributes to coal block deformation ...

A theoretical model for gas adsorption-induced coal swelling
International Journal of Coal Geology, 2007Abstract Swelling and shrinkage (volumetric change) of coal during adsorption and desorption of gas is a well-known phenomenon. For coalbed methane recovery and carbon sequestration in deep, unminable coal beds, adsorption-induced coal volumetric change may cause significant reservoir permeability change.

Swelling and Gas Release in ZnO
Journal of the American Ceramic Society, 1980Swelling and gas release in a model ceramic system, ZnO, were studied under known internal and external pressures, oxygen partial pressures, and temperatures. When gas was not released, the instantaneous swelling strain rate was: εα( DF exp‐Q/RT) where DF

Abstract Dilatometric studies were carried out on three coal samples in various gaseous environments. The carbon contents of the three samples were 65.8%, 78.3% and 83.8% d.a.f., respectively. The sample with the lowest carbon content has shown the maximum length increase (0.5%) on exposure to a CO 2 atmosphere. This corresponds to a volume increase

Measurement of Swelling for PP/Gas Mixtures
SAE Technical Paper Series, 2005<div class="htmlview paragraph">Foaming of thermoplastic polyolefins (TPO) and thermoplastic elastomers (TPE) is gaining interest because of the lightweight and high performance to weight ratio of foamed automotive parts. Since foaming will occur mainly in the PP matrix in these PP-based automotive materials, understanding of the thermophysical ...

Kinetics of Gas-Bubble Swelling in Silver
Journal of Applied Physics, 1971A nondestructive method has been used to monitor continuously the volume changes in thin-walled tubes of oxygen-bearing silver which were heated in an argon ambient containing a few percent hydrogen. A large direct current was used to heat the samples while their ends were water cooled.

Reversibility of fission gas swelling in uranium
Journal of Nuclear Materials, 1969Abstract The effect of hydrostatic pressures up to 1000 bar on the behavior of pre-formed bubbles in irradiated uranium has been studied. High pressure, 900 °C anneals cause the fission gas swelling, induced in uranium by 600 °C vacuum anneals, to be reversed. Subsequent high temperature (900–1080 °C) vacuum tests produce the same swelling as samples
