| Abstract |
CO2 hydrate formation with additives in the pipeline was simulated by the CFD tool of the COMSOL Multiphysics. The length and diameter of the pipeline for the hydrate formation simulation were 1 m and 0.0347 m, respectively. The 3D axis-symmetric geometric structure was implemented. The Eulerian multiphase flow model was introduced for the modelling of the hydrate formation processes composed of complex multi-physical phenomena such as mass transfer, heat transfer, and phase change. The validity of the simulation results was proved by comparing them with previous experimental data in terms of hydrate formation rate. As a result, hydrate velocity and volume fraction along length direction were calculated. The average hydrate mass fraction increased from 8% to 12% by additive. |
