    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.

We review the development of diffuse-interface models of hydrodynamics and their application to a wide variety of interfacial phenomena. These models have been applied successfully to situations in which the physical phenomena of interest have a length scale commensurate with the thickness of the interfacial region (e.g.

With this in mind, we re-view in this section the ideas and applications of diffuse-interface models of a single-component fluid.

An alternative approach consists in so-called diffuse interface methods, based on implicit interface capturing. 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.

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. We also present numerical solutions of the three methods and perform characteristic numerical experiments for two-phase fluid by: Computer Methods in Applied Mechanics and Engineering() Thermodynamically consistent simulation of nonisothermal diffuse-interface two-phase flow with Peng–Robinson equation of Cited by: Skip to Article Content; Skip to Article InformationCited by:.
