The main factor affecting the economics of foam-assisted water alternative gas (FAWAG) process is the loss of foaming agent by adsorption onto reservoir rocks. In this study, the effects of phases, surfactant concentration, salinity, adsorbents, and sacrificial agent on adsorption density were investigated by special adsorption experiments. Moreover, a series of FAWAG tests were performed to ex...

The radio properties of powerful extended radio sources may be used to estimate the ambient gas density in the vicinity of radio lobes. A sample of 27 radio lobes from 14 radio galaxies and of 14 radio lobes from 8 radio loud quasars was constructed using sources from the published literature with suucient radio information to allow an estimate of the ambient gas density. The ambient gas densit...

Design of optimal microstructures for infiltrated solid oxide fuel cell (SOFC) electrodes is a complicated process because of the multitude of the electrochemical and physical phenomena taking place in the electrodes in different temperatures, current densities and reactant flow rates. In this study, a stochastic geometric modeling method is used to create a range of digitally realized infi...

The high dislocation density (ρd) in Fe-C and/or Fe-N martensite is known to be one of the main causes its overall yield strength. Experiments indicate that and, therefore, strength low and medium C steels, follows a well defined behavior with respect background concentration (co). In present work, we introduce model based on finding after γ→α′ sufficiently accommodate/trap most available inter...

The method for the extinction correction based on the gas column density is tested. A positive correlation is found between the total gas column density and the extinction estimated using amodel based on energy conservation (‘frequencyconverter model’). Assuming a Solar Neighbourhood opticaldepth–to–gas ratio, extinction is predicted from the gas column density using a radiative transfer model ...
