We introduce a variational model for multi-phase image segmentation that uses a multiscale sparse representation frame (wavelets or other) in a modified diffuse interface context. The segmentation model we present differs from other state-of-the-art models in several ways. The diffusive nature of the method originates from the sparse representations and thus propagates information in a Author: Julia A. Dobrosotskaya, Weihong Guo.

A phase-field model is a mathematical model for solving interfacial problems. It has mainly been applied to solidification dynamics, but it has also been applied to other situations such as viscous fingering, fracture mechanics,, hydrogen embrittlement, and vesicle dynamics. The method substitutes boundary conditions at the interface by a partial differential equation for the evolution of an.

Instead of treating the material interface as infinitely thin or sharp the diffuse interface techniques replace the discontinuity between two fluids with a transition zone that contains a rapid but smooth variation of the volume by: There are several physico-chemical processes that determine the behavior of multiphase fluid systems – e.g., the fluid dynamics in the different phases and the dynamics of the interface(s), mass transport between the fluids, adsorption effects at the interface, and transport of surfactants on the interface – and result in heterogeneous interface properties.

At the fluid-fluid interface the value of ϕ smoothly varies from –1 to 1 over a finite distance (hence, the term ‘diffuse interface’).

The fluid properties at any location in the domain can be written in terms of the individual properties and the phase field variable as (1) ρ (ϕ) = ρ − 1 − ϕ 2 + ρ + 1 + ϕ 2, η (ϕ) = η Cited by: 4. Abstract. Diffuse interface models have become an important analytical and numerical method to model two-phase flows.

In this study, wake of an elliptic cylinder is analyzed in the presence of a fluid–fluid interface. The interactions between the interface and flow affect each other and hence different wake dynamics and interface topologies are observed.

The models are based on modified Navier–Stokes and interface evolution equations. We present the basic concepts behind these approaches and discuss the advantages and disadvantages of each method.

The diffuse interface method assumes that the interface is described by the spatial variation of a variable. In the VOF method, this is the scalar representing the limit between two fluids. In level set methods, this is the level function itself.

Diffuse interface methods are an approach to modeling dynamic multiphase systems. The method allows keeping track of domains of phases and assign physical tension to interfaces in between.

In this thesis, two diffuse interface methods are applied to study two different kinds of problems. some attention was diffuse interface viscoelastic models that might be able to span the realms from fluid to solid mechanics.

Similarly, upon further investigation, these methods did not appear to provide the most promise for practical simulations. As an alternative, a good deal of effort was spent pursuing overlapping mesh simulations. In this. Her book on the theory and implementation of discontinuous Galerkin methods is highly cited.

The project's topic is on dynamic wetting, where diffuse interface modeling alleviates the known moving contact-line paradox (stress singularity at no-slip walls). However, with phase-field methods, also one could think of other (more exotic) interfacial physics (foaming, crystal growth, etc.), which certainly makes this model class very appealing.
