“…However, some authors report the effects of temperatures on the two-phase porous flow behavior. 5,[27][28][29][30][31][32][33][34][35][36][37][38][39][40] Sinnokrot et al 27 determined the effects of temperature on capillary pressure curves through measurement of drainage and imbibition capillary pressures for three consolidated sandstones and one limestone core. Lo and Mungan 41 proposed that oil recovery operations are more efficient at higher temperature.…”

“…Nutt 28 showed that the displacement of oil by other fluids is affected by capillary bundle size (pore size volume), pore size distribution, interfacial force, interfacial tension, and viscosity ratio, besides showing that at higher temperature faster oil recovery rates are observed. Davis 29 experimentally investigated the effects of temperatures on the P c -S relationships for water-oil and water-air modes by using a mixture of hydrocarbon oil in two silica sands with different grain sizes, concluding that the temperature changes have a major effect on the residual wetting and nonwetting phase saturation while having a negligible effect on capillary pressure. Davis 29 argued that in water-oil systems, the residual wetting saturation increases as the temperature increases, whereas the residual nonwetting saturation decreases as the temperature increases.…”

in Wiley Online Library (wileyonlinelibrary.com).Work carried out in the last decade or so suggests that the simulators for multiphase flow in porous media should include an additional term, namely a dynamic coefficient, as a measure of the dynamic effect associated with capillary pressure. In this work, we examine the dependence of the dynamic coefficient on temperature by carrying out quasi-static and dynamic flow simulations for an immiscible perchloroethylene-water system. Simulations have been carried out using a two-phase porous media flow simulator for a range of temperatures between 20 and 80 C. Simulation domains represent 3-D cylindrical setups used by the authors for laboratory-scale investigations of dynamic effects in two-phase flow. Results are presented for two different porous domains, namely the coarse and fine sands, which are then interpreted by examining the correlations between dynamic coefficient(s) and temperature, time period(s) required for attaining irreducible water saturation, and the dynamic aqueous/nonaqueous phase saturation and capillary pressure plots. The simulations presented here maintain continuity from our previous work and address the uncertainties associated with the dependency of dynamic coefficient(s) on temperature, thereby complementing the existing database for the characterization of dynamic coefficients and subsequently enabling the users to carry out computationally economical and reliable modeling studies.

The air permeability coe‹cient and the radius of vacuum in‰uence are important parameters in the design of soil vapor extraction systems for removing volatile organic chemicals, but procedures for obtaining these parameters have not yet been established. We developed procedures using previously derived analytical equations for the relationship between air discharge rates from an extraction well and the air pressure head generated in the neighborhood of the extraction well in soil with a uniform degree of water saturation in order to obtain these parameters in soil with varying degrees of water saturation. We veriˆed that these procedures could be used to obtain these parameters by using air permeability test data fromˆve sites. In addition, we demonstrated that these procedures could also be applied to gravel soil with fast air ‰ow.

Are Copper(I) Carbenes Capable Intermediates for Cyclopropanations? The Case for Ylide Intermediates

A novel approach is used to synthesize a stable, ligated copper(I) carbene in the gas phase that is capable of typical metal carbenoid chemistry. However, it is shown that copper(I) carbenes generally undergo rapid unimolecular rearrangements including insertions into copper-ligand bonds and Wolff rearrangements. The results indicate that most copper(I) carbenes are inherently unstable and would not be viable intermediates in condensed-phase applications; an alternative intermediate that is less prone to rearrangements is required. Computational data suggest that ylides formed by the complexation of the carbene with solvent or other weak nucleophiles are viable intermediates in the reactions of copper(I) carbenes.
