Water Seepage in Rocks at Micro-Scale

To complete groundwater diversion, the complex flow law of in rocks must be investigated so that diversion can improved. This research uses computer finite element method (FEM), CT scanning calculation method, Avizo and digital core technology combined with Fluent (FCM) to reconstruct microscopic pore structures on a computer. The numerical simulation results under different conditions show that: total pressure change gradually decreases gradients. In seepage channel, path does not pressure, velocity is largest center pore. longer is, greater decrease velocity. Different directions have similar laws. provide effective guidance for project control groundwater.
