Upscaling of Solute Transport in Heterogeneous Media with Non-uniform Flow and Dispersion Fields
Zhijie Xu, Paul Meakin
An analytical and computational model for non-reactive solute transport in periodic heterogeneous media with arbitrary non-uniform flow and dispersion fields within the unit cell o…
Phase field and level set methods for modeling solute precipitation and/or dissolution
Zhijie Xu, Hai Huang, Xiaoyi Li +1
The dynamics of solid-liquid interfaces controlled by solute precipitation and/or dissolution due to the chemical reaction at the interface were computed in two dimensions using a…
Phase-field modeling of two-dimensional solute precipitation/dissolution: Solid fingers and diffusion-limited precipitation
Zhijie Xu, Paul Meakin
Two-dimensional dendritic growth due to solute precipitation was simulated using a phase-field model reported earlier [Z. Xu and P. Meakin, J. Chem. Phys. 129, 014705 (2008)]. It w…
A dissipative particle dynamics model of biofilm growth
Zhijie Xu, Paul Meakin, Alexandre Tartakovsky +1
A dissipative particle dynamics (DPD) model for the quantitative simulation of biofilm growth controlled by substrate (nutrient) consumption, advective and diffusive substrate tran…
A diffuse-interface model for smoothed particle hydrodynamics
Zhijie Xu, Paul Meakin, Alexandre Tartakovsky
Diffuse-interface theory provides a foundation for the modeling and simulation of microstructure evolution in a very wide range of materials, and for the tracking/capturing of dyna…
A phase field approach to no slip boundary conditions in dissipative particle dynamics and other particle models for fluid flow in geometrically complex confined systems
Zhijie Xu, Paul Meakin
Dissipative particle dynamics (DPD) is an effective mesoscopic particle model with a lower computational cost than molecular dynamics because of the soft potentials that it employs…
