We present a transient experimental analysis of the DCMIX1 project conducted onboard the International Space Station for a ternary tetrahydronaphtalene, isobutylbenzene, n-dodecane mixture. Raw images taken in microgravity environment using the SODI (Selectable Optical Diagnostic) apparatus which is equipped with two wavelength diagnostic were processed and the results were analyzed in this work. We measured the concentration profile of the mixture containing 80% THN, 10% IBB and 10% nC12 during the entire experiment using an advanced image processing technique and accordingly we determined the Soret coefficients using an advanced curve-fitting and post-processing technique. It must be noted that the experiment has been repeated five times to ensure the repeatability of the experiment.
我们展示了在国际空间站上针对三元四氢萘、异丁基苯、正十二烷混合物开展的DCMIX1项目的瞬态实验分析。使用配备了两种波长诊断功能的SODI（可选光学诊断）设备在微重力环境下拍摄的原始图像进行了处理，并在本工作中对结果进行了分析。在整个实验过程中，我们使用先进的图像处理技术测量了含有80%四氢萘、10%异丁基苯和10%正十二烷的混合物的浓度分布，并相应地使用先进的曲线拟合和后处理技术确定了索雷特系数。必须指出的是，该实验已重复进行了五次，以确保实验的可重复性。
