This work is part of an international project for the research on the transport properties in ternary mixtures. Six different teams have analysed the same mixture by independent techniques in order to compare the results and validate the techniques. This work is the contribution of the team of Mondragon Unibertsitatea for ground conditions measurements. This team has measured the thermodiffusion coefficients by the thermogravitational techniques and the molecular diffusion coefficients by the Sliding Symmetric Tubes technique. The Soret coefficients have been determined by the combination of the thermodiffusion and molecular diffusion coefficients. The mixture chosen for the study is the one formed by 1,2,3,4-tetrahydronaphtalene, isobutylbenzene and n-dodecane at mass fraction of 80% of THN, 10% of IBB and 10% of n C12, and at 25°C. The good agreement between the results of the different teams shows the validity of the techniques used in this work.
这项工作是一个关于三元混合物传输特性研究的国际项目的一部分。六个不同的团队通过独立技术分析了同一混合物，以便比较结果并验证这些技术。这项工作是蒙德拉贡大学团队在地面条件测量方面的贡献。该团队通过热重力技术测量了热扩散系数，并通过滑动对称管技术测量了分子扩散系数。索雷特系数是通过热扩散系数和分子扩散系数的组合确定的。用于该研究的混合物是由1,2,3,4 - 四氢萘、异丁基苯和正十二烷组成，质量分数分别为80%的THN、10%的IBB和10%的正十二烷，温度为25°C。不同团队的结果之间的良好一致性表明了本工作中所使用技术的有效性。
