A Modification of the Theory of the Thermal Diffusion Column

摘要

Thermal diffusion measurements were made for the system argon‐neon over a pressure range from 4–108 atmospheres. It is found that the classical theory of Furry, Jones, and Onsager is inadequate to describe the results obtained on a series of carefully constructed thermal diffusion columns. A modification of their theory, based on a more complete picture of the behavior of the column, is developed which fits the data satisfactorily. It is predicted and confirmed by experiment that even though turbulence occurs over part of the gap, a separation will occur, and may even be enhanced by this turbulence.
