Abstract

The computer simulation on formation of methane hydrate of clathrate hydrate type I is carried out by molecular dynamics method. The simulated objective is a single cubic unit cell of hydrate type I containing 46 water and 8 methane molecules. The initial configuration is that 46 water molecules is randomly located in the cubic cell of length 12.0A. The MCY and LJ potential model is used for interaction between water molecules and between different molecules. After 26ps running time, methane hydrate is formed at 275K. The stereo computer animation for whole process of molecules' motion approaching to hydrate structure is obtained in conclusion.
