Level-Set and Phase-Field Methods: Application to Moving Interfaces and Two-Phase Fluid Flows
نویسنده
چکیده
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 numerically using an explicit finite difference scheme. In the second part, a conservative level set method, introduced by Olsson and Kreiss [2], is used for simulation of incompressible two-phase flows. Several two-phase test-cases are considered, including rising bubble and falling droplet. Differences between the current methods and the original level set method are highlighted.

TOPOLOGY OPTIMIZATION OF PLANE STRUCTURES USING BINARY LEVEL SET METHOD AND ISOGEOMETRIC ANALYSIS
This paper presents the topology optimization of plane structures using a binary level set (BLS) approach and isogeometric analysis (IGA). In the standard level set method, the domain boundary is descripted as an isocountour of a scalar function of a higher dimensionality. The evolution of this boundary is governed by Hamilton–Jacobi equation. In the BLS method, the interfaces of subdomai...

In this paper, a numerical study is conducted in order to compare hyperbolic range of equations of isotherm two-fluid model governing on two-phase flow inside of pipe using conservative Shock capturing method. Differential equations of the two-fluid model are presented in two forms (i.e. form I and form II). In forms I and II, pressure correction terms are hydrodynamic and hydrostatic, respecti...

In some case of laboratory and industrial applications, various kind of measurement instruments must be placed in a conduit, in which multiphase fluid flows. Vortex shedding for any immersed body in flow field is created with a frequency, which according to flow conditions such as flow rates, geometry of body, etc. may be constant or variable. Failure may happen, if this frequency is close to o...
متن کاملThe Indication of Two-Phase Flow Pattern and Slug Characteristics in a Pipeline Using CFD Method
Multiphase flows are commonly encountered in oil and gas industries. The transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the Baker chart. The effects of small downward inclinations of ...
