摘      要：Dynamic modeling and numerical simulation of hydrate slurry flow behavior are of great importance to offshore hydrate *** this purpose, a dynamic model of hydrate agglomeration was proposed in this *** on population balance equation, the frame of the dynamic model was established first, which took both hydrate agglomeration and hydrate breakage into ***, the calculating methods of four key parameters involved in the dynamic model were given according to hydrate agglomeration *** four key parameters are collision frequency, agglomeration efficiency, breakage frequency and the size distribution of sub particles resulting from particle *** the whole dynamic model was built, it was combined with several traditional solid–liquid flow models and then together solved by the CFD software FLUENT ***, using this method, the influences of flow rate and hydrate volume fraction on hydrate particle size distribution, hydrate volume concentration distribution and pipeline pressure drop were simulated and analyzed.
