| Research Abstract |
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.
