We simulated methane hydrate dissociation in a water-rich sand layer by 3D CFD method with unstructured grid systems. We modeled the sand layer as a calculation domain of face-centered cubic lattice. In this sand layer, we suppose 3 cases of computational conditions. The First case is liquid single-phase condition, the second is bubble-existing two-phase condition, and the last is bubble-generation condition. By this simulation, we got penetration and dissociation rates, and compared them to existing experimental data. Finally we conclude that the present method can simulate actual dissociation phenomenon well.
