In this year, we performed comprehensive studies on the dissolution of trapped phase in porous media.We investigated the effect of wettability on the trapped phase and the dissolution process. By using, non-aqueous phase liquids as the trapped phase and immersing the porous media under octadecyltrichlorosilane, the wettability of the system can be altered from water wet to non-water wet. The dissolution mass transfer was then performed and investigated. The results were summarized and published in Science of The Total Environment.We also investigated the effect of different gases on the dissolution of trapped gases. By changing the gas with different properties, such as density, solubility, and diffusion coefficient, we elucidate the unique dissolution behavior of trapped CO2 gas and also developed the non-dimensional number model relations of various gases under various flow rate. Some of the results were summarized and published in Journal of the Mining and Materials Processing Institute of Japan. Other parts are now analyzed and will be submitted as an academic paper soon.Another work is related with peculiar phenomenon called as dissolution fingering. By changing the porous media characteristics, we observed the formation of dissolution fingering when the porous media to particle size ratio is large enough. The effects of this dissolution fingering to the dissolution mass transfer rate were summarized and published as a research paper in Water Resources Research.

在这一年里，我们对多孔介质中捕获相的溶解进行了全面的研究，我们考察了润湿性对捕获相和溶解过程的影响。通过使用非水相液体作为捕获相并将多孔介质浸没在十八烷基三氯硅烷下，可以将系统的润湿性从水润湿改变为非水润湿。然后进行溶解传质并进行研究。研究结果已发表在Science of The Total Environment上。我们还研究了不同气体对捕获气体溶解的影响。通过改变气体的密度、溶解度和扩散系数等性质，阐明了CO2气体在不同流速下的溶解行为，建立了不同气体在不同流速下的无量纲数模型关系。部分研究结果已在日本矿业与材料加工研究所杂志上发表。其他部分已经分析完毕，即将作为学术论文提交。另一项工作是关于溶解指进现象。通过改变多孔介质的特性，观察到当多孔介质与颗粒粒径比足够大时，溶解指状现象的形成。这种溶解指进对溶解传质速率的影响被总结并作为研究论文发表在《水资源研究》上。
