Binary gaseous diffusion coefficients of zinc in hydrogen, helium and argon at 1 atmosphere and 720–1120 K Using a capillary leak method the binary diffusion coefficients for the gaseous systems Zn+H2, Zn + He, and Zn + Ar were determined as 6.86 × 1... Arthur,Finch,Peter,... - 《...
1.4.1Gaseous diffusion approach According toEl-Sharkawi (2015),gaseous diffusionwas first developed by Jesse Wakefield in 1934 during the development of the Manhattan Project. In 1940, the gaseous diffusion technology was further developed by German scientist Francis Simon and Hungarian scientist Nicholas...
solvent molecules must be pushed out of the way. For this reason, liquid-phase interdiffusion coefficients are inversely proportional to both the viscosity of the solvent and the effective radius of the solute molecules. Accurate theories of diffusion in liquids are still under development.SeeViscosity...
In this work, we present a model, based on rough hard-sphere theory, for the tracer diffusion coefficients of gaseous solutes in non-polar liquids. This wo... YA Aljeshi,MBM Taib,JPM Trusler - 《International Journal of Thermophysics》 被引量: 0发表: 2021年 Diffusion of quercetin in comp...
For the first time, this method was developed by Carniglia (1986) to obtain the effective diffusivity of gaseous species in oxidants and catalysts. And then, it was later employed by Blondeau et al. (2003), who amended it for the estimation of the diffusion coefficients in building materials...
摘要: The use of empirical power laws to calculate the diffusion coefficients of gases is considered. The method of similitude is used to obtain generalized relations which permit the calculation of the diffusion coefficients of gases in temperature ranges not covered by experiment....

The technique is appropriate for measuring D//e in the range of 10** minus **2 to 10** minus **8 cm**2/s. Comparisons between this technique and other techniques are discussed. Diffusion of two binary gaseous systems in a nuclear graphite and in a bituminous coal has been studied......
