A CRITICAL REVIEW ON MASS DIFFUSION COEFFICIENT MEASUREMENT OF FLUID

摘要

In the past five decades, theoretical and experimental research on mass diffusion pheonama have attracted much interest because of many potential application. In this paper, on the basis of reviewing a large number of references, the existing experimental methods of measuring mass diffusion coefficient and their scope of application were introduced thoroughly, the measuring theory and the characteristic of each method is introduced also, and a comparison was made between all these methods. In recent years，mass diffusion coefficients of a number of substances or new substances have been measured, a summary is provided in the paper. As the extensive use of alternative fuels, the mass diffusion coefficient of vehicle fuel have been measured by our group, the experimrntal data are also summarized.
