In this study, the gas–water–hydrate–sand four-phase flow characteristics were simulated using the Eulerian model and a user-defined function for hydrate particle diameter in fluent. The results indicate that (1) in the straight pipe section, hydrates concentrated in the middle and lower regions, wh...
