Numerical simulation of 2-D explosive field of gas

In this paper, applying the theory of gas explosion, numerical simulation of the problem of coal gas explosion is studied. During the process of simulation, the condition of the outside force, the outside resources and the heat exchange are ignored; the partial differential conservation equations of the compressible fluid are given by adopting the fluid model. The "and" splitting scheme to resolve the transport step by using MMIC (Multi-Material in cell) method is adopted. The calculation format of this problem is given. And through the post-process by using visualization software we get the cartoon simulation result of 2-D explosive field of gas, through which we can see the process of the explosion of gas clearly.
