| As the green energy-saving storage medium, hydrates are increasingly favored by researchers at home and abroad. While the new method, hydrate molecular dynamics simulation, which can be analyzed and studied from the microscopic point of view, has gradually become the mainstream of development. In this paper, the molecular dynamics simulation of hydrate formation in recent years is summarized. It analyzes the basic simulation methods for hydrate formation, and explores the effects of different factors on hydrate formation from the perspective of nucleation and growth. The results show that different thermodynamic conditions, interface properties and the addition of the third component will affect the formation of hydrates. It is considered that the establishment of more reasonable and efficient models, explore the broader hydrate characteristics, and find environmentally friendly and efficient inhibitors are the main direction of future research. |
