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].
