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

Figure 2

Equivalent, incircle, and hydraulic diameters of fluid-occupied pores within hydrate-bearing and hydrate-free porous media. (a) A pixel map of a rectangular pore occupied by fluids within hydrate-bearing porous media. Light gray pixels stand for the fluid-occupied pore with side lengths of 5 and 6 px, while dark gray pixels represent solid particle and hydrate pixels. Area of the pore is , and perimeter is . Symbol represents the minimum distances of pore pixels to solid particle and hydrate pixels, and the maximum value in the rectangular pore is 3 px. (b) Values of equivalent , incircle , and hydraulic diameters for the rectangular pore shown in (a). (c) Values of intrinsic maximum equivalent , incircle , and hydraulic diameters in hydrate-free artificial porous media shown in Figure 1(a).
