Moving mesh method for direct numerical simulation of two-phase flow with phase change

E. Gros; G. Anjos; J. Thome

Vol. 339 pp. 636-650 ISSN 0096-3003

Keywords: Finite element method (FEM), Phase change, Axisymmetric, Two phase flow, Arbitrary Lagrangian–Eulerian (ALE)

A moving mesh approach is employed to simulate two-phase flow with phase change. The mathematical model is based on the Arbitrary Lagrangian-Eulerian (ALE) description of the axisymmetric Navier-Stokes equations and...

Rising Bubble in a Vertical Slowly Diverging Pipe

Gustavo Anjos; E. Gros; Selvam K.; J. Peixinho

Foz do Iguaçu, Brazil

Keywords: rising bubble, instability, interface, diverging pipe

We present the results of a combined experimental and numerical study of an air bubble rising in a vertical slowly diverging pipe in a stagnant liquid. Initially, the bubble is confined in a cylindrical tube and rises...

An ALE-FEM Method for Axisymmetric Two-Phase Flows

Erik Gros; Gustavo Rabello dos Anjos

Keywords: interface, arbitrary Lagrangian-Eulerian, Finite Element Method, Rayleigh-Taylor instability, rising bubble

The present work aims at developing a computational framework to simulate macro and microscale two-phase flows in axisymmetric coordinates. An important application is the microchannels that will be used for the cooling...
