Dufour effect in liquid mixtures

Rastogi and Madan [2] investigated Dufour effect in liquids for the first time. They employed a simple experimental set-up as shown in Fig. 5.2 for the purpose. [Pg.86]

Later on, improved technique was employed by Rastogi and Yadava [12, 13] for investigation of Dufour effect in several liquid mixtures. Diffusion coefficient was also measured. D estimated from the data has been compared with those for thermal diffusion coefficients estimated from the known data on Soret coefficient using measured values of diffusion coefficients. Although AT is found to be = 0.3°C, the values of D and D are on reasonable agreement. [Pg.86]
