CFD Analysis of Normal Shock using Shock Tube with Five Species

A shock tube is equipment that can produce a moving normal shock wave produced by the sudden bursting of diaphragm separating a high pressure gas section from one at lower pressure gas section. It is used in high speed test facilities. The objective is to solving shock tube problem with CFD code is to calculate the fluid flow property and observed how fluid parameters are varies with time because of shock tube used for high speed test and finding out the behavior of normal shock in the test field. In the present study, dimensional Euler equations are used as governing equation. The spatial discretization is carried out by unstructured cell-centered Finite Volume Method. Here the convective fluxes are evaluated using Van Leer Flux Splitting Scheme. Species transport equations are also added in the Euler equation for treatment of non-reacting mixing of the gas.
