Non Ideal Gas Flow Simulation: a New Formulation of Conservation Equations

摘要

The analysis of real gas flow has a particular importance for the development and the optimisation of rocket engines. The aim of our study, which is a part of the CARINS (CAIculs de Reseaux INStationnaires) program, is to develop a numerical code to solve the complex unsteady real gas flows encountered in the regenerative cooling of a rocket engine. For that purpose, a high resolution total variation diminishing scheme was adopted. Its accuracy and robustness properties are reviewed on shock tube experiments for perfect and Van der Waals gases. The numerical results show a good agreement with previous literature results.
