Experimental Investigation and Numerical Simulation using Smoothed Particle Hydrodynamics for Water Absorption into Soil

Abstract

Soil contamination is one of the main environmental issues. Insoluble treatment is an important method to improve contaminated soil. In order to solve the problems of insoluble treatment, a simulator to represent the interaction between solid and liquid was developed using Smoothed Particle Hydrodynamics (SPH) method. The simulator replicated a water flow with an error rate of 2% and a permeability test with an error rate of 4%. For water absorption into dry silica sand No.9, the simulation result became more realistic by concerning soil suction.
