Application of AUSM schemes to multi-dimensional two-phase flow problems

In this paper we study the extension of AUSM schemes to multi-dimensional two-phase flow problems with phase change. We present the system of equations characterizing these problems, the closure relationships and the equations of state to close the system. We present some of the most important characteristics of the numerical method used in this work, discribing how primitive variables are determined from conserved variables. Numerical results, corresponding to a fast depressurization benchmark, are included and compared with some experimental data. Conclusions are then drawn and future work briefly described.
