A sharp interface capturing approach is presented for two-phase flow simulations with phase change. The Gradient Augmented Level Set (GALS) method is coupled with the two-phase momentum and energy conservation equations to advect the liquid-gas interface and predict heat transfer with phase change. The Ghost Fluid Method (GFM) is adopted to discretize the advection and diffusion terms for veloc...

This paper presents a stencil adaptive phase-field lattice Boltzmann method (LBM) for the simulation of two-dimensional multiphase flows. In the phase-field model, the interface is viewed as a layer with finite thickness where physical parameters vary steeply and continuously. In the present study, a phasefield LBM is used. In this model, the Cahn–Hilliard equation can be correctly recovered by...

In this paper we describe findings related to user interface requirements for live electronic music arising from research conducted as part of the first three-year phase of the EUfunded Integra project. A number of graphical user interface (GUI) prototypes developed during the Integra project initial phase are described and conclusions drawn about their design and implementation.

We study interface and vortex motion in the two-component dissipative Ginzburg-Landau equation in two-dimensional space. We consider cases where the whole system is divided into several domains, and we assume that these domains are separated by interfaces and each domain contains quantized vortices. The equations for interface and vortex motion will be derived by means of a variational approach...

Adaptive user interfaces are commonly used for providing different layouts and information according to the current context-of-use. However, the complexity and heterogeneity of potential users, platforms and environments lead to a combinatorial explosion of variants, making it almost impossible to foresee all potential results of adaptations at design time. In this paper we present our work on ...

The main focus of this paper is to introduce, in a thermodynamically consistent manner, an anisotropic interface energy into a phase field theory for phase transformations. Here we use a small strain formulation for simplicity, but we retain some geometric nonlinearities, which are necessary for introducing correct interface stresses. Previous theories have assumed the free energy density (i.e....

For interface-tracking simulation of two-phase flows, we propose a new computational method, NS-PFM, combining Navier-Stokes (NS) equations with phase-field model (PFM). Based on the free energy theory, PFM describes an interface as a volumetric zone across which physical properties vary continuously. Surface tension is defined as an excessive free energy per unit area induced by density gradie...

The present problem deals with the propagation of Love-type surface waves in a bedded structure comprises of an inhomogeneous orthotropic layer and an elastic half-space. The upper boundary and the interface between two media are considered to be corrugated. An analytical method (separation of variables) is adapted to solve the second order PDEs, which governs the equations of motion. Equations...

It is well understood that the adsorption of solutes at the interface between a bulk liquid crystal phase and an aqueous phase can lead to orientational or anchoring transitions. A different principle is introduced here, whereby a transient reorientation of a thermotropic liquid crystal is triggered by a spontaneous flux of water across the interface. A critical water flux can be generated by t...

New variational principles are developed for the e}ective heat conductivity tensor of aniso! tropic two!phase composites in the presence of coupled mass and heat transport processes at the two!phase interface[ We focus on physical situations where an imposed temperature gradient causes impurities or lattice defects to concentrate on the two!phase interface and di}use along it[ This is accompani...
