The simulation of NAPL contamination effects in steady-state two-phase flow in a single filled fracture based on lattice Boltzmann method

In this paper, the NAPL contamination transportation concerning with the wettability in the single filled fracture was studied by the Shan-Chen multi-component multiphase lattice Boltzmann model. With the help of the model, the contact angle of the non-wetting phase and wetting phase interface at a solid wall is adjustable. By considering a set of appropriate boundary conditions, the fractured conductivity under the NAPL contamination blocks the channels in the single filled fracture was investigated. The conductivity K f is dependent of the NAPL contamination content. The different Simulated results show that the lattice Boltzmann method is a very instrumental method for simulating and studying the immiscible multiphase flow problems in single filled fracture.
