Numerical Simulation of Seepage in Plastic Percolation Irrigation Pipes Embedded Underground

摘要：

The coupling model of waters flowing in pipes and migration in soil body was built on the theory of fluid mechanics in porous media and hydrodynamic theory. Navier-Stokes equation was used to control the flowing of water in percolation irrigation pipes, and Darcys law was used to simulate the migration of water in soil body. COMSOL Multiphysics which is multi-physical analyzing software was adopted, and the set-up numerical model was simulated and analyzed. The results showed that it was suitable when pressure head was 2m and the distance between plastic pipe and crop roots was 30mm.
