With the aim of providing reliable benchmark values, we have measured the Soret, thermodiffusion and molecular diffusion coefficients for the ternary mixture formed by 1,2,3,4-tetrahydronaphthalene, isobutylbenzene and n-dodecane for a mass fraction of 0.8-0.1-0.1 and at a temperature of 25°C. The experimental techniques used by the six participating laboratories are Optical Digital Interferometry, Taylor Dispersion technique, Open Ended Capillary, Optical Beam Deflection, Thermogravitational technique and Sliding Symmetric Tubes technique in ground conditions and Selectable Optical Diagnostic Instrument (SODI) in microgravity conditions. The measurements obtained in the SODI installation have been analyzed independently by four laboratories. Benchmark values are proposed for the thermodiffusion and Soret coefficients and for the eigenvalues of the diffusion matrix in ground conditions, and for Soret coefficients in microgravity conditions.
为了提供可靠的基准值，我们测量了由1,2,3,4-四氢萘、异丁基苯和正十二烷形成的三元混合物在质量分数为0.8 - 0.1 - 0.1且温度为25°C时的索雷特系数、热扩散系数和分子扩散系数。六个参与实验室所使用的实验技术包括地面条件下的光学数字干涉测量法、泰勒色散技术、开口毛细管法、光束偏转法、热重力技术和滑动对称管技术，以及微重力条件下的可选光学诊断仪器（SODI）。在SODI装置中获得的测量结果已由四个实验室独立分析。本文提出了地面条件下热扩散系数和索雷特系数以及扩散矩阵特征值的基准值，以及微重力条件下索雷特系数的基准值。
