摘要

Transient separation of the individual components in a multicomponent liquid mixture in a thermogravitational column can be used to determine the thermal and molecular diffusion coefficients.Two models of the transient behavior are developed.First,a classical model where density only depends on temperature.Second,a general model where the compositional effect on density is also taken into account.Diffusion coefficients can be determined by fitting experimental data to either model.The procedure is demonstrated for a ternary liquid mixture.The results reveal that the classical model is very unreliable even though composition variation only contributes to the total buoyancy by one-third.Diffusion coefficients can be obtained reliably from the general model provided the experimental noise does not exceed±1 of steady-state separation.This level of accuracy in composition measurements is achievable.
