摘要CO2在航空燃油中的质量扩散规律对飞机油箱惰化系统的研究极其重要。搭建压力降法实验装置测量CO2在RP-3航空燃油中的扩散系数,实验测试了-20、0、20、40和60℃恒温条件下的CO2气相空间压力随时间变化关系。根据Fick定律建立了容器中二维扩散方程,并采用数值解法,设定
Determination of the interparticular effective diffusion coefficient for CO2 and O2 in solid state fermentation A simple experimental diffusion controlled fermentor (DCF), coupled with the use of a mathematical model based on mass balance, is proposed to measure the ...

The CO2-effective diffusion coefficient is a key parameter in the modelling of carbonation of cementitious materials. It is usually deduced from empirical relationships determined by tests on mixtures made with Ordinary Portland Cement (OPC). These relationships are a priori non-valid for materials ...

Rates of diffusion in gases increase with the temperature (T) approximately asT3/2and are inversely proportional to the pressure. The interdiffusion coefficients of gas mixtures are almost independent of the composition. Kinetic theory shows that the self-diffusion coefficient of a pure gas is invers...
predictive tool for describing the diffusivity in amorphous polymer-solvent solutions above and below the glass transition temperature. The present work focuses on various applications of the Vrentas-Duda free volume theory to correlate and predict the mutual binary diffusion coefficient in polymer-solvent...
