Phase-field modeling of two-dimensional solute precipitation∕dissolution: solid fingers and diffusion-limited precipitation.
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 was shown that diffusion-limited precipitation due to the chemical reaction at the solid-liquid interface has similarities with diffusion-limited aggregation (DLA). The diffusion-limited precipitation is attained by se...
متن کاملAutomaton Model of Precipitation / Dissolution Coupled with Solute Transport
Precipitation/dissolution reactions coupled with solute transport are modelled as a cellular automaton in which solute molecules perform a random walk on a regular lattice and react according to a local probabilistic rule. Stationary solid particles dissolve with a certain probability and, provided solid is already present or the solution is saturated, solute particles have a probability to pre...
متن کاملLevel-Set and Phase-Field Methods: Application to Moving Interfaces and Two-Phase Fluid Flows
Level Set and Phase Field methods are well-known interface-capturing techniques for approximation of moving interfaces. In the first part of this project, a recently developed sharp-interface phase-field method [1] is implemented in Matlab and used to implicitly capture normal interface motion and interface advection by an external velocity field. The interface evolution equation is solved nume...
متن کاملPEIECWISE CONSTANT LEVEL SET METHOD BASED FINITE ELEMENT ANALYSIS FOR STRUCTURAL TOPOLOGY OPTIMIZATION USING PHASE FIELD METHOD
In this paper the piecewise level set method is combined with phase field method to solve the shape and topology optimization problem. First, the optimization problem is formed based on piecewise constant level set method then is updated using the energy term of phase field equations. The resulting diffusion equation which updates the level set function and optimization ...
متن کاملDistance Field Reinitialization for Localized Level Set Methods
Bibliography 83 Preface Since their introduction by Osher and Sethian [14], level set methods have been used to solve a wide range of problems, including, but not limited to • Photolithography Development, Etching and Deposition in Semi-conductor Manufacturing (see [2]), • Robotic Navigation with Constraints (see [9]). More examples of applications, further references, and a survey can be found...
