Level-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...

Numerical Simulation of Two-phase Flows Using a Hybrid Volume of Fluid and Immersed Boundary Method

In this paper a simulation model is presented for the Direct Numerical simulation (DNS) of multiphase flow. This method combines the Volume of fluid model and Immersed Boundary method in order to investigate water-oil flow-pattern. The simulations were carried out on structured cartesian adaptive mesh refinement (SAMR), where the the Immersed Boundary represents the circular tube via Direct For...

Immersed boundary methods for the numerical simulation of incompressible aerodynamic and fluid-structure interactions

In this work three branches of Immersed Boundary Methods (IBM) are described and validated for incompressible aerodynamics and fluid-structure interactions. These three approaches are: Cut Cell method, Vortex-Penalization method and Forcing method. Two first techniques are validated for external bluff-body flows and the last one is used for fluid-structure interactions. The paper confirms the a...

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

Immersed Boundary Methods

The term “immersed boundary method” was first used in reference to a method developed by Peskin (1972) to simulate cardiac mechanics and associated blood flow. The distinguishing feature of this method was that the entire simulation was carried out on a Cartesian grid, which did not conform to the geometry of the heart, and a novel procedure was formulated for imposing the effect of the immerse...
