Soret効果のWirtz理論ノート

抄録

-The Soret coefficient of dilute solutions may be derived by the same method as Wirtz's kinetic Treatment. The smoothed potential model of liquids was considered for calculating Soret coefficient of dilute solutions. It is shown that there might be the additional term -1/2T to the Soret coefficient, (q_L-q_H)/kT², derived from the harmonic occillatos model of liquids.
Therefore, the thermal diffusion coefficient D′ will not be expressed correctly by the Wirtz's relation between the diffusion coefficient D and the thermal diffusion coefficient D′, D′=dD/dT.
The heat of treatment will be represented by q_H-q_L+kT/2, where the term kT/2 corresponds to the heat of tranport in knudsen gasses.
