Maximum Sizes of Fluid-Occupied Pores within Hydrate-Bearing Porous Media Composed of Different Host Particles

Figure 4

Normalized maximum equivalent , incircle , and hydraulic diameters of fluid-occupied pores within hydrate-bearing porous media evolving with hydrate saturation . Normalized maximum equivalent diameter for grain-coating (a) and pore-filling (b) hydrates. Normalized maximum incircle diameter for grain-coating (c) and pore-filling (d) hydrates. The blue solid dot curve in (d) is drawn by when and when . Normalized maximum hydraulic diameter for grain-coating (e) and pore-filling (f) hydrates. (g) A fitting model and its parameter values for descriptions of different pore diameters changing with hydrate saturation. The fitting model is drawn as black dashed curves in (a–f).
