Film formation mechanism of CO_2 hydrate in dissociation temperature

本研究旨在揭示CO_2水合物成膜机理、膜厚的影响因素，以及水合物对模拟海底充填床注入液态CO_2流动的影响。结果表明，随着温度和流速的升高，CO_2水合物膜厚度减小。通过对摩擦系数的比较，得出水合物对液态CO_2流动的影响随着雷诺数的增加而减小。

The purpose of this study is to reveal the film formation mechanism of CO_2 hydrate, the influential factor of the film thickness, and the influence of the hydrate on the flow of liquid CO_2 injected in a packed bed as simulating seabed. As the result, the measured CO_2 hydrate film thickness decrease with increase in temperature and flow velocity. As the result of comparing friction factor, it is suggested that the influence of the hydrate on the flow of liquid CO_2 as flow resistance becomes small as Reynolds number increases.
