| Abstract: | A one-dimensional numerical model of heat transfer during gas hydrate film formation on gas-liquid interface is suggested by analyzing the process of the static system. According to the rate of gas consumed, the relation between the thickness of hydrate film and time can be obtained. The temperature distribution of different phase in the system is analyzed and the effect of temperature distribution of water is confirmed. The result indicates that it is effective to accelerate the rate of hydrate formation by enhancing the heat transfer in water phase. |
