Abstract
In this paper, an arbitrary Lagrangian Eulerian (ALE) based numerical method
has been presented for the numerical simulation of gas-particle two phase flow
with moving boundaries. The main stages for the implementation of the
algorithm have been discussed. The numerical results of cylindrical implosion
and 2D dusty gas explosion have shown the effectiveness of the method.
Keywords: ALE method, compatible Lagrangian method, gas-particle two phase
flow.
1 Introduction
Gas-particle two phase flow is a complex flow phenomenon in the natural
environment and industrial engineering. With the development of physical
modeling, numerical investigation has been playing a more and more important
role in the research field. For most numerical investigation, the physical domain
is fixed, thus the Eulerian numerical methods are generally used with fixed grid
and fixed boundaries. However, for the investigation of the strong interaction of
gas-particle two phase flow with structure where the solid structure deformation
is severe and the physical boundary is moving, the numerical method should
have the ability to track the moving boundary (also the fluid-structure interface)
and a moving grid is need. In this paper, an arbitrary Lagrangian Eulerian (ALE)
based numerical method is presented for gas-particle two phase flow with a
trajectory model, which satisfies the above requirements [1, 2].
