Abstract

The goal of this study is to gain an understanding of the computational challenges for the numerical simulations related to the experiments on the NASA Electric Arc Shock Tube (EAST). The paper focuses on the spurious numerics which take place in numerical simulations of the problems containing stiff source terms and discontinuities. Some results of the previous study on the spurious behavior of numerical methods are given first. Then the results of the 1D and 2D EAST simulations using a simplified physical model are presented. The obtained results illustrate the phenomena that the discontinuity locations depend on grid spacing and numerical method for this problem.
