Abstract: A fully three-dimensional (3D) multiphase flow model (3DMPS) is developed to simulate the migration of three phases (water, non-aqueous phase liquid and gas) using a fractional flow formulation for the governing equations. ...

Abstract: This paper proposes a particle tracking technique for applying the Eulerian–Lagrangian localized adjoint method or the Eulerian–Lagrangian method to solve transport equations in a rapidly changing unsteady flow. The proposed ...

Abstract: This study proposes a numerical model for gas- and water-phase solute transport describing the change in leachate quality and gas production by microbial activities in a sanitary landfill. The proposed model includes gas ...

Abstract: This study compares various leachate management scenarios using a biologically reactive transport model, which is proposed in this study. The proposed model can be used to predict the contribution of biodegradation to ...
