represents the realistic pore structure of the media, was constructed. With this model, three dimensional pore scale fluid flow among particles was simulated. Then the distributions of fluid flow velocity... space. Figure 4 shows that the velocity decreases gradually from the center of pore throat and body to the surface of particles and reaches zero finally. The fluid flow mainly occurs in the connected pore......
