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…
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…
Phase-field modeling of solute precipitation and dissolution
Zhijie Xu, Paul Meakin
A phase-field approach to the dynamics of liquid-solid interfaces that evolve due to precipitation and/or dissolution is presented. For the purpose of illustration and comparison w…
