Shocktube Studies of Gas-Liquid Reactions and of Gas-Phase Diffusion. Part II. Improved Analysis of Gas Phase Diffusion Coefficients

摘要

Continued development of a method for measurement of diffusion coefficients of gases for wide ranges of temperature and pressure is described. A shocktube provides experimental conditions, and diffusivity of the gas is inferred from the rate of absorption of carbon dioxide in triethanolamine behind a reflecting shock wave. Revised analysis of data previously reported (see AD-641 435) demonstrates that the experimental results are of good precision. A new apparatus, capable of use at stronger shock conditions, is described briefly. Additional study of liquid-phase and gas-phase chemical and physical phenomena is necessary before reliable diffusion coefficients can be reported. (Author)
