during a certain time interval (t) in a medium whose coefficient of diffusion (D) is known,Dbeing equal to one-half the average of the square of thedisplacementin thex-direction. This formula for probability “density” allowsPto be plotted againstx. The graph is the familiarbell-shaped ...
The gas diffusion coefficient in soil (DP), and its dependency on soil physical characteristics, governs the diffusive transport of oxygen, greenhouse gases, fumigants, and volatile organic pollutants in agricultural, forest, and urban soils. Accurate models for predicting DP as a function of air-...
Saturated Elasto-Plastic Porous Media under Consideration of Gaseous and Liquid Phase Transitions Taking a closer look on, e.g., storage processes of greenhouse gases in deep geological aquifers or pressure changes in shear bands, the observation can be... W Ehlers,T Graf - Springer Berlin Heide...
Determination of the diffusion coefficient of vapors in gases by Stefan's method leads to results of rather low reliability. Improvement can be attained by using a recording microbalance. The determination is performed by recording the loss of weight of a small bucket containing a liquid evaporating...
also compared with those predicted theoretically from solvent viscosity by the relationships of Einstein, Eyring, Longuet-Higgins and Pople, Ree, Ree and Eyring, and Houghton, the purpose being to find a physical explanation for the observed variation of diffusion coefficient with solute molecule size...
A mathematical model that describes both the transient and steady-state response of a single spherical porous catalyst pellet to a step input in concentration of a dilute binary gas mixture is presented. The model equations, which contain the effective diffusion coefficient of the dilute binary as ...
Values of diffusion coefficients obtained by this method are compared with previous measurements for two of the gases, and satisfactory agreement is found. Coefficients are given for the diffusion of CO 2, NH 3, SO 2, Cl 2 and Br 2 in air at 20°C and 760 mm Hg pressure. 展开 ...
The approach provided a feasibility to evaluate the gas-liquid diffusion coefficient by analyzing the temporal evolution of the oxygen spot area on the experimental images. The second method was conducted through a flat air-liquid interface in a Hele-Shaw cell filled with quiescent deoxygenated water...
